These libraries have grown in coverage by the fastest rates since their inception. The EI library will contain spectra of over 306,000 compounds, an increase of nearly 40,000 from the 2020 version. The Retention Index library showed a corresponding increase. The Tandem library will double in coverage, with the number of compounds increasing to over 27,000 – including 1.2 M spectra and 288 K precursor ions. [NIST, 2020]
NIST20 consists of new and enhanced versions of:
- NIST/EPA/NIH Electron Ionization (EI) Mass Spectral (MS) Library;
- NIST non-spectral data;
- NIST Tandem (MS/MS) Library (also sold separately);
- NIST GC Method / Retention Index Library (also sold separately);
- NIST Mass Spectral Search (MS Search) Program, with new AI Retention Index (RI) estimates;
- MS Interpreter, with major updates; and
- Automated Mass Spectral Deconvolution and Identification System (AMDIS), updated in 2019.
NIST20 contains major enhancements over NIST11:
The NIST/EPA/NIH Mass Spectral Library: This release contains 306,622
electron ionization (EI) spectra of 306,869 different chemical
compounds — an increase of nearly 40,000
compounds from the previous release (NIST17). Spectra for Human \& Plant Metabolites, Food/Flavor/Fragrance, Drugs \& their Metabolites, Forensics, Toxins, Pesticides \& Contaminants, Industrial Chemicals, Petrochemicals, Surfactants, Lipids, etc.
The NIST Tandem (MS/MS) Library has 31K compunds, twice that in NIST17, with 186K precusor ions and 1.3M spectra. Fragmentation methods include High-Resolution Accurate Mass (HRAM), 28K compounds; QTOF, HCD, IT-HRAM, and QqQ, 30K compounds; Ion Trap, 29K compounds; and APCI HRAM, 246 compounds. Precursor Ion Types include 27K Protonated, 13K Depronated, 10K Water/Ammonia Loss, and 24K other in-source generated. More than half of the compunds and spectra are metabolites, with 6K human metabolites.
