The NIST MS/MS Library 2020 is a collection of MS/MS Spectra and search software. It is included in the complete NIST MS 2020 database (of EI, MS/MS, and GC data), but the MS/MS portion can also be purchased separately, as described here. The search software is based on the widely used NIST MS Search.

Main Features

This product is a subset of the NIST Standard Reference Database 1A NIST/EPA/NIH MASS SPECTRAL LIBRARY (NIST 2017), and the MS/MS database has also been expanded for 2020. It also includes the NIST MASS SPECTRAL SEARCH PROGRAM Version 2.4 for use with Microsoft® Windows™.

Many other NIST MS/MS Peptide libraries are available for download free of charge at http://peptide.nist.gov .

System requirements:

This MS search program is a 32-bit Windows application and thus requires Windows XP SP3, Vista, Windows 7, 8, 8.1, 10. 2 GB disk space.

New features of the 2017 program and database

  • MS/MS Library Expansion: Greatly expanded NIST 17 MS/MS Library. Spectra include metabolites, peptides (biologically active peptides and all di-peptides and tryptic tri-peptides), contaminants, metabolites, lipids and more.
  • New HiRes MS/MS Hybrid Search type. Uses the logic of normal searching and the logic of neutral loss searching.
  • Types of Any Peak search: HiRes peak and HiRes loss
  • Display additional MS/MS information in hit lists
  • Edit accurate peak m/z, intensities and peak annotations in the built-in mass spectrum editor
  • MS/MS Precursor m/z search
  • Precursor type constraint. Restrict MS/MS spectra in search results to specific precursor types, exclude isotopic precursors, display MS3 and higher spectra in addition to MS2. Works with NIST 17 nist_msms library. Rejects spectra which do not have correct Precursor type syntax. This is in addition to other filters for MS/MS spectra to limit hits by charge, precursor type, instrument, msn, and mass accuracy.
  • Spectrum polarity filter
  • See What's New in the main NIST web page for additional details on these changes.

New features of the 2014 program and database:

New features of the 2011/2012 program and database:

Some noteworthy features of the program and database are:

  • MS/MS browsing window and MS/MS library
  • New type of mass spectrum search: MS/MS Identity search for searching for MS/MS spectra in MS/MS libraries. The updated Lib2NIST converter is a tool for creating MS/MS libraries. To create a MS/MS library, run Lib2NIST and check "MS/MS spectra only" option. For the MS/MS search to work, the MS/MS spectra must contain precursor m/z values. The previously named Similarity "MS\MS" search has been renamed to Similarity "MS/MS in EI" mass spectral library search.
  • Structure searching - the program will find all chemical structures similar to the structure of the search spectrum. The searching can be done using structural data from the NIST MS database, from the user database or from a structure drawn in most chemical drawing packages. A structure may be exported to chemical drawing software. The Structure similarity search algorithm has been changed: now it Includes homologue recognition that generates a match factor of 1000 for homologs. Homologs may be excluded from the hit list. You will need to rebuild structure search databases in user libraries (as you usually need to do after editing a user library containing structures.)
  • Searching in the Contributor/Comment spectral records and extracting tagged fields into the displayed spectrum text information.
  • Drag and Drop - Data can be dragged and dropped between windows. Point mouse to the name of the compound in the spectrum plot window, press and hold the left mouse button, drag the spectrum and drop it into Spec List or Compare Window.
  • User Library Structures - This feature has been present for some time, but many are unaware of it.
  • Compare Views - There are a number of different ways for you to visually compare two spectra.
  • Direct interaction with a number of chemical drawing packages - the clipboard can be used with some of them, most can be used by use of intermediate files.
  • The NIST MS Search program takes advantages of many normal Windows conventions. Look at the context sensitive options on the right mouse button click and on buttons at the top of the window. Look also for "Keyboard shortcut keys" in the index to the Help or search Help for "short cut keys"
  • Thermodynamics-based MS Interpreter program version 2.0. A spectrum with a structure may be sent to MS Interpreter by right-clicking the windows with a mass spectrum and structure and selecting Send To MS Interpreter. A spectrum and/or structure may be pasted or dragged and dropped into the Mass Spectrum or Structure panes of MS Interpreter.

Additional Details

Demo/Evaluation

You can get some idea of the operation from the NIST MS full version demo, but that only contains sample EI spectra, not MS/MS spectra. You may instead download the NIST peptide demo, which contains a sample MS/MS library of peptides (but not small molecules). See also screenshots of the small molecule MS/MS library library in NIST MS/MS.
