Identify it with NIST 17, the world’s
most widely trusted mass spectral library!

Mass Spectral Library &Search Software

Upgrade discount for any previousversion. Agilent format option.
Compatible with most mass spectral data systems,
including Agilent ChemStation/ MassHunter,
Thermo Xcalibur, Waters MassLynx, Shimadzu
GC/MS Solutions, and others.

NIST 17 contains nearly a million mass spectra:
306,000+ electron ionization (EI) spectra for 267,000+ compounds.
652,000+ tandem MS/MS spectra:
176,000+ ion trap spectra for 120,000+ ions of 14,000+ compounds
475,000+ collision cell spectra for 39,000+ ions of 14,000+ compounds

NIST 17 also contains search software to matchyour spectra against spectral libraries.
Each spectrum has corresponding information, such as• chemical formula, structure, and mass
• chemical names, synonyms, CAS#, InChiKey (PubChem)• GC method and retention indices if applicable (72,000+ in EI library)

Quality, broad coverage, and accessibility— these are what the NIST MS Library is
known for, a product of a three decade,comprehensive evaluation, where eachspectrum is validated for correctness by ateam of experienced mass spectrometrists.
Additional utilities bundled with NIST 17:
AMDIS - extracts noise-free component spectra from GC/MS data files
and can library search them withNIST MS Search
MS Interpreter - assists in analysis andinterpretation of mass spectra (NewVersion)

NIST Libraries & Search Software
The included NIST MS Search Software allows browsing and searching the EI MS, MS/MS, and GC libraries.

Given a user provided (unknown) spectrum, library search for the best matching
spectra in the NIST and user libraries. Matches are ranked. Searches may add avariety of constraints (name, elements present, structural similarity, etc.).
Searching is also possible from most mass spectral data systems, including
Agilent ChemStation/MassHunter, Thermo Xcalibur, and others.

The Electron Ionization (EI)
mass spectral library consists of306,622 spectra of 267,376
unique compounds, each with
name, formula, molecular structure (mol), molecular weight,
CAS#/InChIKey, contributor
name, list of peaks, and synonyms.

The GC library contains 404,045 citations of retention indices (Kovats orLee) RI and GC methods for 99,400 compounds (72,361 in the EI library)with structures, covering both polar and non-polar columns. Whenavailable, this data is displayed with the spectrum search results. RI values
can now be displayed in the hit list and used for scoring.

The MS/MS library contains 652,475 tandem spectra from ion trap, qTOF, HCD, and tandem QQQ collision cell instruments, most acquired under electrospray. Spectra can be browsed by mass, formula, and energy from the MS/MS
tab or library searched against your own spectra or search criteria. Details on experimental conditions on each library
spectrum are displayed.

The Mass Spectrum Interpreter utility assists in theevaluation of mass spectra. You can examine neutral losses,
isotope patterns and possible chemical formulas, along withcomputer-assisted chemical structure/spectra analysis.

The NIST AMDIS utility integrates with NIST MS Search for• GC/MS deconvolution: Preprocesses GC/MS or LC/MS
data files, automatically reconstructing spectra fromcomplex mixtures. Selected compounds can then be sent
to the NIST MS Search software for library searching.
• Chemical Identification: Can also act as a “black box”
chemical identifier, displaying all chemical identifications
that meet a user-selectable degree of confidence.
Identification can be aided by internal standards andretention times.

New in NIST 17
All libraries have undergone substantial enhancements in the 2017 release.
• EI MS Library: 30,000+ new EI spectra. Expands coverage of metabolites and designer drugs, as well as the application of new computer-assisted evaluation methods
for removal of low quality spectra.

Version• MS/MS Library: Nearly 3x increase in the MS/MS library. Spectra include metabolites, peptides (biologically
active peptides and all di-peptides and tryptic tri-peptides), contaminants, metabolites, lipids and more.

Updated software - some major new features include• MS/MS Searching• New HiRes MS/MS Hybrid search type uses the logic of normal searching and the logic of neutral loss searching to find many

more similar compounds in the hit list (requires a precursor mass).
• AnyPeak search: New accurate mass peak and loss types.
• MS/MS Precursor m/z search• Precursor type constraint to restrict results to specific precursor types, exclude isotopic precursors, and display MS3
and higher spectra in addition to MS2.
• Spectrum polarity filter• EI MS Seaching• New EI Hybrid Search (Similarity/Hybrid) type uses boththe logic of normal searching plus the logic of neutral loss
searching. Same algorithm as MS/MS Hybrid search withunit charges and nominal MW instead of precursor m/z.
• Presearch for EI Similarity/Neutral Loss search. Elimi-nates restrictions on the maximum loss considered.
• All Searching• An 'InChIKey' presearch for all library spectrum
searches. Finds all spectra which have the same first
InChIKey segment as the search spectrum, and compares them to the search spectrum.
• Improved algorithms for scoring high mass accuracy
searches that account for sparse spectra.
• User interface enhancements.
• New version of MS Interpreter software.
• See “What’s New” on our web page for additional details.
