SIS supplies over 20,000 parts and services for mass spectrometry, chromatography, vacuum, and other scientific equipment.
--The fully-evaluated, most widely used mass spectral reference library. Compiled by the National Institute of Standards and Technology (NIST).
Summary: The NIST 14 mass spectral database, the successor to the NIST 11, 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 14 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.>
Statistics for NIST 11 and earlier versions are given below.

This is a "fully evaluated" collection of electron ionization (EI) mass spectra. It is the product of a more than three 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. 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 276,248 spectra of 242,466 unique compounds. Besides spectra, typical data include name, formula, molecular structure (.mol), molecular weight, CAS number, contributor name, list of peaks, synonyms, and estimated and/or measured retention index.

Most of the MS/MS spectra have been measured on ion trap and collision cell (qTOF, QQQ, and HCD) instruments using electrospray ionization, although spectra from a number of other instrument types and ionization methods are represented.
See NIST 14 MS/MS for details on the MS/MS library.
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 387,463 Kovacs retention indices and corresponding GC methods, column conditions and literature citations for 82,868 compounds. Data include both non-polar and polar columns. Most values were abstracted from the open literature and then compared to replicate values 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].

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.
EI, MS/MS, and GC RI libraries have all undergone substantial enhancements in the 2014 release (see also statistics at the top of this page).
Updated Software: A number of major new features have been added to the search software. The most significant are
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.
Note: The above description reflects NIST 08 (see What's New in NIST 14 for more recent changes).
Figure: NIST MS interpreter
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.

Operating system requirements:
Complete installation (libraries, NIST MS Search program, and AMDIS) requires about 1.4 GB of free hard disk space. The MS search program requires Windows NT 4.0, Windows 2000, XP, or Vista.
Note for Windows NT 4: Latest versiosn of AMDIS, MS Interpreter, and Lib2NIST are not compatible with Windows NT 4.0. 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".
NIST 08 Note: 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.
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]".
Download AMDIS 2.71 (July 2012) (free) (a somewhat older version of this is included in demo and need not be downloaded separately)
Which version to buy? Contact us if you have any questions if unsure.
