Accurate Mass User Libraries in NIST14 Release

Return to Home Page

Users can now add accurate mass EI and MS/MS to their libraries.  This is an updated feature distributed with the recent NIST 14 library and Search software release.  A brochure from a distributor is shown below and also another link to “What’s New”:

I have shown some examples of accurate mass EI and MS/MS spectra in the link below.  The data was obtained on a Waters GCT and processed in MassLynx.

The next link details information from David Sparkman for utilizing FreeStyle.  This application is supplied by ThermoFisher with their Orbitrap (Q Exactive).  It is a stand-alone data processing application that will transfer accurate mass EI data to the NIST search software.  The Qual Browser software within Xcalibur will not export accurate mass data to the NIST search.

The last link contains abbreviated instructions written by J. Little for exporting EI Orbitrap data to NIST using FreeStyle:
