Wiley NIST/EPA/NIH Mass Spectral Library 2023

Maximize MS analysis workflow with expanded coverage in latest release of this essential resource

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!

What's Included:

• Electron Ionization (EI) mass spectral library
• 4 MS/MS libraries
• GC Retention Index (RI) library
• NIST 2023 Software: MS Search, AMDIS, MS Interpreter

Available from Wiley in the most common instrumentation manufacturer formats, NIST 2023 is a necessity for any laboratory engaged in GC-MS analysis.

Accelerate your workflow further with options to access to even more data

The Wiley distribution also offers options to access additional data to ensure the most comprehensive coverage and powerful tools to optimize workflow.
