Food authenticity testing using HRAM Orbitrap GC-MS and Compound Discoverer Software

The high degree of specificity provided by high-resolution accurate-mass capabilities of the Thermo Scientific™ Orbitrap Exploris™ GC mass spectrometer provides the most crucial information for confident elemental composition determination of each observed mass fragment in a mass spectrum. Combining this with new tools in Thermo Scientific™ Compound Discoverer™ software for EI and CI mass spectrum analysis provides a powerful method to identify compounds. 

Furthermore, statistical tools within Compound Discoverer software allow the detection of differences between samples that is required in many application areas, including food authenticity testing. In this demonstration, we will show how easy it is to set up the system and software, perform EI and CI data analysis, and tune and mass calibrate the system.
