Description
Important Notice: The National Institute of Standards and Technology (NIST) released NIST 23 on Monday, June 5, 2023. If you already own a copy of an earlier version of the full NIST Library, you can upgrade to NIST 23, or you can purchase a new license of the full NIST 23 Library.
Upgrade older versions of the Full NIST Mass Spectral Database to NIST 23.
Note: the full NIST 23 library distribution (EI + MS/MS + RI) is > 4GB in size.
Important: Proof of a valid license from an earlier version of the NIST Mass Spectral Library is required before we will ship your order or provide a download link.
This item includes:
- Main EI MS Library: Spectra for 394K chemical compounds.
- Replicate EI MS Library: 46,954 replicate spectra.
- Tandem (MS/MS) Library: 51,501 compounds (60% more than NIST 20).
- Tandem (MS/MS) Library: 400K precursor ions and 2.4 million spectra.
- Retention Index Library: 492K RI values for 153K compounds.
- NIST MS-Search 3.0: The standalone NIST Mass Spectral Search Program.
- AMDIS: The Automated Mass Spectral Identification and Deconvolution System.
Important Information About NIST 23:
- The NIST 23 Mass Spectral Libraries (EI and Tandem) can not be converted to SDF or MSP text file formats using the Lib2NIST program. The ability to do this with previous versions of the NIST Library was accidental, and has been disabled in NIST 23.
For more information on the NIST Mass Spectral Library, see our NIST 23 Library web page, or visit the NIST Mass Spectrometry Data Center web site.
Important: If you are ordering the NIST Library on either DVD or USB media and your shipping address is outside the United States, please review the International Terms and Conditions.
