GC Image has deeply discounted pricing on
the NIST/EPA/NIH Mass Spectral Library (NIST11) with 2012 enhancements of the MS/MS database.
GC Image, a licensed distributor, offers discount pricing of only $1495
for a new license and $1095 for an upgrade from a previous version.
Discounts are available for simultaneous purchase of multiple licenses.
NIST11 consists of new and enhanced versions of:
- NIST/EPA/NIH Electron Ionization (EI) Mass Spectral (MS) Database,
- NIST non-spectral data (also sold separately),
- NIST MS/MS Database with 2012 enhancements (also sold separately),
- NIST GC Methods and Retention Index Database (also sold separately),
- NIST Mass Spectral Search (MS Search) Program (v.2.0g),
- MS Interpreter, and
- Automated Mass Spectral Deconvolution and Identification System (AMDIS).
NIST11 contains major enhancements over NIST08:
NIST has published a What's New in NIST11
and a Historical Perspective of NIST11 with
The NIST/EPA/NIH Database of Electron Ionization Mass Spectra contains
243,893 EI mass spectra of 212,961 different compounds, an increase of
almost 10% over NIST08.
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 include many replacements with higher quality
spectra, a thorough review of chemical names, and merging of the
previous salts library with the main and replicates libraries.
The NIST Database of MS/MS spectra has undergone an even greater
enhancement, with more than double the number of compounds.
Most spectra have been acquired on both ion trap and qtof/triple quad
instruments, thereby increasing the number of spectra by more than
six-fold compared to NIST08.
Spectra for the latter instrument classes have been acquired over a
wide range to energies to ensure matching regardless of instrument
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 2011 version contains 10,665 ion trap spectra for 9,194 different
ions of 4,628 compounds, and 85,344 collision cell spectra (qtof and
triple quad) for 7,172 different ions of 3,877 compounds.
An updated GC Methods and Retention Index Library contains 346,757 GC
Methods with Retention Index (RI) values for 70,835 compounds, a 61%
increase from NIST08.
The number of compounds with with RI data in the EI library is 38,648,
an increase of 76%.
In addition, an Estimated Kovats RI together with a confidence interval
is displayed for many compounds based on the structure associated with
MS Search will calculate RI values for structures submitted by users.
The NIST MS Search Program, now permits high mass accuracy mass searching
and many asked for new features.

of the new NIST MS Search Program.
AMDIS (Automated Deconvolution and Identification System) is significantly
updated for GC/MS analysis.
The new MS Interpreter works with exact mass for both GC/MS and MS/MS
Some components of NIST11 are available separately:
The NIST08 demo version is available here.
The NIST MS Search Program (Version 2.0f, build 8 Oct 2008) and other information about the software is available here.
NIST GC Methods and Retention Index Database
NIST has released the Method / Retention Index Database (which is included in NIST/EPA/NIH MS Library) as a separately available product.
The Retention Index Database package is a comprehensive collection of
gas-phase retention index data together with a standalone search
The search program accesses all RI information contained in the 2011
version of the NIST/EPA/NIH 2011 Mass Spectral Library).
This includes 346,757 annotated Kovats Retention Index (RI) values for
70,835 compounds, a 61% increase in the number of compounds.
The annotations include literature source and measurement conditions.
The number of compounds with RI data in the EI Database, mainlib, is
38,648, an increase of 76%.
In addition, for many compounds in the database an Estimated Kovats
Retention Index (RI) together with a confidence interval is displayed
based on the structure associated with the spectrum.
This product retrieves RI values with their corresponding GC methods
by molecular weight, formula, name, CAS registry number, and, most
importantly, chemical structures that can be submitted from various
Look up can be constrained to elements present, numbers of each element
present, and name strings for the main database name and synonyms
present for many of the compounds contained in this unique Database.
This program also estimates RI values for each compound based on
structure using NIST developed and published algorithms.
Search results can be limited to column type (packed or capillary),
stationary phase type (polar, non-polar), temperature program type
(isothermal or ramped), and data type (Kovats or Lee index).
Each GC method has details about the column length, diameter, and
stationary phase loading along with the full literature citation.
NIST MS/MS Database
The NIST MS/MS Database and Search Program were greatly improved in 2011 and enhanced again in 2012.
The NIST MS/MS 2012 upgrade is available without additional charge (except shipping and handling, if shipped separately) to purchasers of the NIST11 MS Library.
The 2012 version contains 121,586 spectra of 15,180 ions from 6,999 compounds, including metabolites, drugs, peptides (biologically active peptides and all di-peptides and tryptic tri-peptides), surfactants, contaminants, sugars, lipids, and more.
The new MS/MS search tools provide significant new features.
