There are currently two mass determination services offered at CMSI:


1. Low-resolution mass spectrometry (LRMS)

2. High-resolution mass spectrometry (HRMS)


The LRMS service is primarily designed for synthetic chemists and for other researchers who want to find out the mass of products or intermediates for providing information on their reaction or purity of their isolated molecule. Available ion sources: electrospray (ESI) and atmospheric chemical ionization (APCI). The normal service includes training on the LC-MS instrument and providing analytical support for the user to run their own samples. 

The HRMS service is primarily designed for analysis of pure samples to acquire accurate mass. Available ion sources: electrospray (ESI) and atmospheric chemical ionization (APCI). The normal service includes running the samples without a column. You will get a brief report with the detected accurate mass, the ppm error, and a mass spectrum chromatogram of the detected compound.

 

Instrument used for this service: Agilent 6120 SQ MS and Agilent 6520 QTOF.
