NIST 2026 Mass Spectral Library

The new NIST 2026 Library is now available to order. A few highlights:

• EI Spectra increased by 35K more compounds, selected for analytical importance.
• MS/MS Spectra increased by 33% more compounds (3.2M spectra).
• MS Search v4.0 Software: Full Chromatogram Analysis. Unique, extensive multilevel analysis: XIC-based analysis, in-source RT alignment, access external libraries, customize/zoom/sort display, eliminate background MS2, MS1 & MS2 analysis, enhanced hybrid search, export to spreadsheet, and multiple ID methods.
• More details on our web site: www.sisweb.com/nist
