How to Perform a NIST Search for a Mass Spectrum Using Chromeleon or NIST program Directly

Issue

Is there a way to search the GCMS NIST library for a specific compound in Chromeleon?

Environment

• Product model : ISQ, ISQ 7000, TSQ 8000, TSQ 9000
• Application: GC/GCMS, Chromeleon 7.2 and 7.3

Resolution

In order to find the Mass Spectrum of a Compound in NIST and how to navigate to NIST through Chromeleon 7:

Go directly to the NIST program C:\Program Files (x86)\NISTMS\MSSEARCH then NISTMS.exe. your executable may be somewhere else, but should be in this location. 

Alternatively, go through Chromeleon: 

Go to Chromatogram. Right-click. Select Show Spectrum.
Right click on Spectrum and Go to Open Spectrum with NIST.
When NIST opens you can go to Search and then you can search by CAS or several other parameters.
