Overview

Ensure faster analysis with expanded compound coverage in latest release of this essential MS spectral library

One of the most trusted mass spectral libraries has once more been extensively updated. The NIST / EPA / NIH Mass Spectral Library 2023, developed by the experienced mass spectrometry team at the National Institute of Standards and Technology (NIST), represents the culmination of more than four decades of comprehensive evaluation and expansion, making it an essential resource for those analyzing mass spectra.

Take the guesswork out of compatibility. Wiley supports more instrument software than any other NIST 2023 distribution!
