--The fully-evaluated, most widely used mass spectral reference library. Compiled by the National Institute of Standards and Technology (NIST).
Summary: The NIST 11 mass spectral database, the successor to the NIST 08, is a fully evaluated collection of electron ionization (EI) mass spectra. It also contains a growing set of MS/MS spectra and GC data. It is the product of more than two decade, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library by a team of experienced mass spectrometrists in which each spectrum was examined for correctness.
NIST 11 is not just a mass spectral library. It contains these components:
Libraries are formatted the binary format suitable for use alone or by the NIST MS Search software (and AMDIS). Additional instrument-specific formats (e.g. Agilent ChemStation and MassHunter) are available separately to permit library searching directly within your GC/MS or LC/MS data system.
With each purchase, we ship a CD (installs software, libraries, and documentation) and a printed manual.
To check for compounds in the NIST library, you may search names of compounds online.

Note: the following description reflects NIST 08 (see What's New in NIST 11 for more recent changes).
This is a "fully evaluated" collection of electron ionization (EI) mass spectra. It is the product of a more than two decade, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library by a team of experienced mass spectrometrists in which each spectrum was examined for correctness. This has lead to thousands of selections, deletions and modifications to produce an optimal reference library of compound identification by spectrum matching and library searching. Each spectrum has been carefully evaluated, and all decisions regarding selection or deletion were made only after agreement of two experienced mass spectral evaluators, as described in presentations at major conferences. While computer methods assisted in finding chemical identification errors and inconsistencies, and revealed certain varieties of mass spectral errors, manual interpretation was the principal basis for this evaluation effort.
The Electron Ionization (EI) mass spectral library consists of 220,460 spectra of 192,108 unique compounds, each with related data and (nearly always) chemical structure.
Besides spectra, typical data include name, formula, molecular structure (.mol), molecular weight, CAS number, contributor name, list of peaks, synonyms, and estimated retention index.

Note: the following description reflects NIST 08 (see What's New in NIST 11 for more recent changes). The MS/MS Library can also now be purchased separately if you'd like the MS/MS data only.
Most of the MS/MS spectra have been measured on ion trap and collision cell instruments using electrospray ionization, although spectra from a number of other instrument types and ionization methods are represented. Spectra have been provided by contributors, measured at NIST and extracted from the literature. In view of the relatively small size of the library, it is intended primarily to serve as a 'starter set'. It also documents spectrum variations between instruments classes at different conditions. We have found that at sufficiently high signal-to-noise measurement conditions, modern instruments are capable of providing very reproducible, library searchable spectra. While collision energy can be an important variable, spectra varies in an understandable way depending on compound and instrument class and conditions. This Library is provided in formats equivalent to the Electron Ionization Library but with new fields added to describe the instrument and analysis conditions. A small number of MS1 spectra are also included for reference purposes. These generally contain the ions used for MS/MS.
The search software permits the examination of all MS/MS spectra - these are available as a selectable library, with the name 'nist_msms'. A new MS/MS tab has been added to the MS Search Software to view that data.
Further information on the MS/MS sub-library (some of this is from the 2008 and 2011 versions but is still useful):
Gas phase retention data for compounds common to the EI and NIST Retention Data collection are provided with links to the EI library. This involves 192,108 Kovacs indices and corresponding GC column conditions and literature citations for 21,847 compounds, an increase of over 50% from the previous version. Data include both non-polar and polar columns. Most values were abstracted from the open literature and then compared to replicate values (average of 10 per compound) and estimates to find and remove errors. We also continue to provide estimates of retention indices for most compounds in the library using an extension of a method developed earlier for boiling points [2-3].
GC data includes
Here's typical GC data included for a compounds (decanol):

Figure: NIST MS Search software
The updated, full-featured NIST MS Search Program for Windows has a full range of integrated tools. The new updated version of this widely used, full-featured software is designed for identifying compounds from their mass spectra and for exploring mass spectral libraries. It also contains tools for deconvoluting gas/liquid chromatograms and interpreting mass spectra.
This software provides a flexible means of accessing data in the NIST and User libraries including:
When the program is first started, seven tiled windows appear on the screen (the Desktop), each with its own data and behavior. The behavior of any Window may be modified by making it active (clicking on it) and then pressing the AdjustWin button at the bottom of the Desktop. As you become familiar with program operation, you may wish to change the dimensions of some Windows or even close some of them to create a custom Desktop. When the program is restarted, it will begin with the most recent Desktop. To save a window-arrangement Desktop for future use, select Desktop from the Menu Bar and then Save As from the resulting Menu. Prior Desktops may be restored using one of the predefined names or your own name. Such arrangements describe the geometry and type of information shown in each Window, not the actual data contained in it. To restore a previous hit list, select it from the list at the top of the Hit List Window.
Library Searching - Identify unknown compounds and substructures using fully documented and optimized procedures, or search by a wide range of compound and spectral properties.
Library Building - Maintain your own libraries, add your own chemical structures and search using the same optimized procedures developed for NIST.
Flexible User Interface - Set multiple Desktop configurations with up to seven independently configured windows to examine search results and match your needs.
Use with Your Instrument Data Systems - Direct transfer between a number of commercial data systems and the NIST Search Program.
Adding User-Drawn Structures
Users may import their own chemical structures
with selected user spectra. This is done in the Tools/Librarian section
of the program by connecting a user-drawn structure in standard MOL-file
format with a user spectrum. Such structure-drawing programs are
widely available (for example, ISIS/Draw may be freely downloaded
from http://www.mdli.com/prod/freesw.html). As before, if a user
spectrum is given its CAS registry number and the Main Library has a structure
for it, this structure will automatically be shown with user spectra unless
the user has attached an imported structure to the spectrum.
Aids for Automation and Reporting
A variety of methods for automated searching and reporting of results
are available. From the File menu selection, if Print automation
is on, printing will follow each library search. A set of print options
is also available from the "User Search Options" Window (select Search,
then User spectrum). This is of particular use when using this NIST
Program with other data acquisition programs.
The AMDIS software extracts pure component spectra from complex GC/MS or LC/MS data files and searches against specialized libraries or the NIST library. This module was developed at the national Institute of Standards and Technology (NIST) for the critical task of verifying a major international treaty, the Chemical Weapons Convention. After two years of development and extensive testing it is now being made available to the general analytical chemistry community. AMDIS can operate as a "black box" chemical identifier, displaying all identifications that meet a user-selectable degree of confidence. Identification can be aided by internal standards and retention times. Libraries can be built directly from analyzed data files or from spectra in the NIST/EPS/NIH Database. AMDIS can also serve as a preprocessing tool for the GC/MS data files, automatically performing noise reduction for all components. It permits traditional library searching for any selected component. A flexible interface is provided to assist the analysis of complex matrices.
Included as a separate utility, AMDIS attempts to reconstruct original mass spectra for individual components in arbitrarily complex GC/MS and LC/MS reconstructed total ion current (RTIC) chromatograms; and, if a target library is provided, can directly identify target compounds. AMDIS is especially useful when an RTIC chromatographic peak represents multiple components. Regardless of each component's concentration, pure mass spectra are deconvoluted for analyses. AMDIS was developed by NIST for the Defense Weapons Agency (Department of Defense) for verifying compliance with a major international treaty (Chemical Weapons Convention) ratified by the United States Senate in 1997. In order to meet the rigorous requirements for this purpose, AMDIS was tested against more than 30,000 GC/MS data files accumulated by the EPA Contract Laboratory Program without a single false-positive for the target set of known chemical warfare agents. While this level of reliability may not be required for all laboratories, this shows the degree to which the algorithms have been tested.
AMDIS has been designed to reconstruct "pure component" spectra from complex RTIC chromatograms even when components are present at trace levels. For this purpose, observed chromatographic behavior is used along with a range of noise-reduction methods. AMDIS is distributed with specialized libraries (environmental, flavor and fragrance, and drugs and toxins), that were derived from the NIST Library. AMDIS has a range of other features, including the ability to search the entire NIST Library with any of the spectra extracted from the original data file. It can also employ retention index windows when identifying target compounds and can make use of internal and external standards maintained in separate libraries. A history list of selected performance standards is also maintained.
As of version 2.65, AMDIS reads data files in the following formats:
AMDIS may also be downloaded separately.

This utility enables the user to examine neutral losses, isotope patterns and possible chemical formulas along with computer assisted chemical structure/spectral analysis. Starting with Version 1.5, the program has offered a unique means of interpreting spectra of compounds not identified in the Library by the User spectrum search. This is most useful when no acceptable matching spectra are found in a User spectrum search of the NIST Library. At this point, by selecting Substructure Information from the Tools menu, the current hit list is analyzed and statistical information on the composition of the unknown is derived from the hit list. For instance, the probability that any of a range of substructures are present or absent are listed (phenyl, acid, ester group, double bond, heteroatom, etc.) along with an estimate of the molecular weight and chlorine/bromine content (the latter is based only on the spectrum itself).
This tool was developed to aid NIST evaluators in their analysis of mass spectra. In one integrated program, it permits a wide range of calculations on a mass spectrum using--if available--a proposed chemical structure. Spectra and structures are associated in the library facility of the Windows Search Program discussed above, and the program is activated from the Tools menu. Peaks in the spectrum originating as a logical fragment of the molecule are marked, and corresponding fragments may be highlighted. It also allows the analyst to keep track of important neutral losses, both from the parent or a derived ion, and to readily compute possible formulas for any peak or neutral loss and isotopic patterns as desired. Observed isotopic clusters can be compared to theoretical predictions subject to a number of user-specified constraints.

NIST11 consists of
The NIST/EPA/NIH Database of Electron Ionization Mass Spectra now contains 243,893 carefully evaluated spectra for 212,961 compounds, an increase of nearly 10% from the 2008 version. This includes 23,433 new spectra of metabolites, drugs of abuse, derivatives of common compounds and many more, all measured specifically for this library. Other major enhancements have been made to the prior version including many replacements with higher quality spectra, a thorough review of chemical names and merging of the previous salts library into the main library.
The NIST Database of MS/MS spectra has undergone an even greater enhancement. The new collection more than doubles the number of compounds represented. Further, most spectra have been acquired on both ion trap and qtof/triple quad instruments, thereby increasing the number of spectra by over a factor of six compared to the 2008 version. Spectra for the latter instrument classes have been acquired over a wide range to energies to ensure matching regardless of instrument collision settings. Also, when available, high mass accuracy spectra are stored. New spectra include metabolites, peptides (biologically active peptides and all di-peptides and tryptic tri-peptides), contaminants, lipids and more. The near-final version contains 9,934 ion trap spectra for 9,138 different ions of 4,649 compounds, and 91,557 collision cell spectra (qtof and tandem quad) for 6,939 different ions of 3,774 compounds.
There have been a number of enhancements made to the NIST MS Search Program; not the least of which is the addition of an Exact Mass Search and the ability to sort Hit List by the number of synonyms and other databases (non-mass spectral databases) in which the compound can be found. Features introduced in NIST08, like the ability to use the EI Database and the Substructure Identification Tool in the interpretation of CAD spectra and the ability to display isomers and derivatives as replicate spectra, have been retained and are still available. Figure 1 shows one view of the new look of the Hit List window and Text Information window in the Lib Search Window of MS Search v.2.0g.
The NIST MS Search Program, since its introduction as a Windows version (v.2.0), has evolved into a power tool for not only the matching of spectra of unknown compounds against spectra for that compound in the EI and MS/MS Databases, but also the identification of unknowns encountered in toxicology, forensic, quality control, flavor and fragrances, environmental and many other fields through their mass spectra, regardless of the type of ionization or the analyzer used to determine the abundances of ions sorted according to their m/z values. The EI Database contains much more than just the mass spectra of compounds. It contains a primary and in many cases multiple synonyms including common and trade names. It contains names of other databases where specific compounds can be found, the name of the contributor, the compound��™s elemental composition, its nominal and exact mass, and the compound��™s chemical structure.
The NIST MS Search Program can be an invaluable tool in GC/MS method development through the use of the GC Method/RI Database, exposed in the NIST MS Search program. This utility can also be enhanced by the addition of the new NIST GC Method/RI Search Program, which can be used by itself in the GC laboratory. The NIST MS Search Program has evolved out of the needs of those in the NIST Mass Spectrometry Data Center that use it and the Databases on a daily basis. Many user suggested enhancements have been add to the Program which is distributed with NIST11.
The following is lists a number of new features available in the NIST MS Search Program v.2.0g. Only by exploring, using the Help available in the Program and looking at the electronic manual that is provided will it be possible to begin to see all the features and benefits. Only through extensive utilization and practice will it be possible to see the entire picture available with the NIST MS Search Program.

As shown in Figure 5, the information preceding each equal sign (=) will be displayed as a Field title in the Text display of the spectrum and can optional be displayed with the Plot of the spectrum. The information following the equals sign (=) will appear following the Field header. Entry of Field contents (string) must conform to the rules above. In order for this display to occur, the Field titles must be registered in the Display comment field options dialog box shown in Figure 4 (View/Comment fields options). When the Tags have been entered into the Comment Field Options dialog box, they will not be displayed in the Comments field of the Text Information window. Figure 5 shows a spectrum (Plot and Text) with added Field headers.
When a search is done of a User library that contains Tags (Field titles), it is possible to Constrain that search based on the Tag (Field title) and the partial or whole contents of the Tag (Field title). More specific details on the use of Tags as Constraints are in MS Search Help and Manual.
The Substructure Identification Tool indicated that there were probabilities ≥90% that the unknown contained one are more atoms of oxygen, had a R+dB count greater than five, that it contained both a methyl and a methylene group and that there was a substructure with both connected to one another, and a carbonyl group. There were probabilities >85% that the unknown contained one or more atoms of nitrogen, that there was an aromatic ring and a heterocyclic ring with nitrogen, a carbon oxygen bond, and many other substructures.
The probability of the absences of substructures showed a >90% probability that there was not a phenyl carbonyl or phenyl methoxy, a dialkyl ether, an oxygen in a ring, benzyl moiety, an alkyl-aryl ether, or an aryl nitro group. Using these reported presences and absences it was not too difficult to establish a probable structure as shown to the left. Not only can the Substructure Identification tool be used in the evaluation of CAD (MS/MS Spectra), it can also be used in the identification of unknowns using spectra when there is no spectrum for the unknown in a database.
NIST 08 made the following major changes since NIST 05.
Electron Ionization (EI) Library: The new library consists of 220,435 spectra of 192,262 compounds an increase of 15% over the previous version. NIST has, at the same time, continued to improve overall library quality by re-measuring and reexamining thousands of spectra. For example, it has been provided consistent identification for hundreds of salts and created a separable collection of low-volatile substances not expected to be measurable by GC/MS (717 spectra of 672 salts). Thousands of spectra of common derivatives and contaminants measured at NIST or by close collaborators have been added. As before, all compounds are represented by both names and chemical structures.
GC Data Library: Includes 224,038 Kovacs indices for 21,847 compounds, an increase of over 50% from the previous version. Data include both non-polar and polar columns (NIST 05 had only non-polar columns). Most values were abstracted from the open literature and then compared to replicate values (average of 10 per compound) and estimates to find and remove errors.
MS/MS Spectra: This release greatly expands our collection of MS/MS spectra by 250% to 5,308 different precursor ions. A large fraction of the new spectra are for contaminants and metabolites.
Some enhancements were also made to the MS Search Software, such as
NIST 05 made the following major changes since NIST 02.
EI Library: This now contains 190,825 spectra of 163,198 different chemical compounds. In addition to the new spectra, important quality improvements have been made in both spectra and compound identification information. The binary format has not changed from the 2002 version, although several new files have been added that associate equivalent compounds and link individual compounds to the retention index library (see below).
GC Data: This is a new addition, containing 121,112 Kovats Retention Index values for 25,893 compounds on nonpolar columns, 12,452 of which are compounds represented in the Electron Ionization Library. Full annotation is provided, including literature source and measurement conditions. These are provided in a format accessible by our Search Program.
MS/MS Library: This is a new addition, containing 5,191 spectra of 1,943 different ions (1,671 positive and 341 negative ions).
Latest new features in the program and database:
NIST 02 made the following major changes since NIST 98 and previous versions.
The previous version (NIST 98) provided for a 75% increase in coverage and this latest release (NIST 02) provides for an additional 35% increase in coverage. This was accomplished primarily by the addition of complete, high quality spectra either measured specifically for the library or taken from major practical collections, including:
NIST 02 contains spectra of more than 147,000 compounds along with associated chemical identification data including chemical structures, synonyms, and other of relevant information. The best quality spectra are placed in the Main Library; and good-quality, alternate spectra are provided in the Selected Replicates Library, bringing the total number of spectra to about 175,000. This release represents the largest increase in both quality and coverage in the 25-year history of the NIST/EPA/NIH Mass Spectral Database--and for the first time that it can be stated that the library has been fully evaluated. The objective of this effort was to provide the best possible reference library for compound identification by mass spectral library searching.
Operating system requirements:
Complete installation (libraries, NIST MS Search program, and AMDIS) requires ~400 MB of free hard disk space. The MS search program requires Windows NT 4.0, Windows 2000, XP, or Vista.
Note for old ChemStations (B1701BA): the error about $_ undefined can be resolved by replacing $_(number, string) with string in the ChemStation macros. Contact us for instructions if you run into this.
Note for Windows NT 4: You may need to download the older AMDIS version 2.63. Running 2.66 on NT 4 gives the error "AMDIS_32.EXE - Entry Point Not Found - The procedure entry point MonitorFromPoint could not be located in the dynamic link library USER32.dll".
Download NIST 08 Demo. The demo differs from the full version of NIST 08 mainly in that it contains a very small subset of the database. Also, this is a demo of only the standard version of NIST (does not contain native formats in the ChemStation and multiformat versions of NIST). Note: a demo version of the newer NIST 11 release is not available, but the software looks and operates similarly.
Note: In order for your MS data system to recognize the demo version, you may need to edit the file "c:\windows\win.ini" (or "c:\winnt\win.ini") to change the line "[NISTMSDEMO]" to "[NISTMS]".
