Wiley Science Solutions New Mass Spectral Libraries

Now Updated: The Original and Broadest Combined Mass Spectral Library Available

In the modern analytical and bio-analytical laboratories, rapid and accurate identification and reliable analysis of drugs, poisons, pollutants, metabolites and other substances has never been more crucial or complex.  The collection of spectral libraries from Wiley and NIST provide essential tools for general unknown identification in analytes ranging from aerosols and VOCs to complex biologicals and organics.

The latest releases of the Wiley Registry 11th Edition/NIST 2017, NIST/EPA/NIH Mass Spectral Library 2017, and NIST/EPA/NIH MS/MS Mass Spectral Library 2017 continue to evolve accounting for today’s research demands and high laboratory standards. These mass spectral libraries include the recently improved NIST MS Search software (2.3v), including significant improvements in search algorithms as well as the addition of hybrid searching for EI and MS/MS to find spectra for compounds that differ by one inert group.

Wiley Registry 11th Edition/NIST 2017 Mass Spectral Library

The ‘Wiley Registry 11th Edition/NIST 2017’ library contains over 1.6 million EI and MS/MS mass spectra, making it the most comprehensive combined mass spectral library available.  The new release contains more than 1 million EI mass spectra, 730,000 unique compounds, and over 973,000 searchable chemical structures. Replicate spectra and over 3 million chemical names and synonyms provide a higher rate of correct identification and ensure that the library can aid in classical EI, exact mass, and other methods of identification.

NIST/EPA/NIH Mass Spectral Library 2017

Thoroughly updated and more comprehensive than ever, the 2017 release of ‘NIST/EPA/NIH Mass Spectral Library’ is the one of the most trusted, versatile mass spectral data collections ever published. It is made up of three libraries, an Electron Ionization (EI) mass spectral library, a MS/MS library, and a GC Retention Index library.

NIST/EPA/NIH MS/MS Mass Spectral Library 2017

Newly expanded for its 2017 release, ‘NIST MS/MS Spectral Library’ contains more than twice the spectra of the 2014 release at 652,475 and more than two times the number of ions at 123,881. The library has been expanded to now cover small molecules, di and tri peptides, metabolites, designer drugs, surfactants, and commercially available peptides. Of the included 123,881 ions there are 1,436 biologically-relevant peptides.

Wiley’s spectral libraries are compatible with all of the leading manufacturer formats. This helps ensure transportability when switching instruments or manufacturers, and takes the guesswork out of ordering for mixed-instrument deployments.
