Application Note: Analysis of Drugs of Abuse and Explosives by GC-MS
1 March 2016
Researchers from Prof. Guido Verbeck’s group at the University of North Texas (UNT) carried out analysis of drugs of abuse (DOA) and explosives using an ion trap GC-MS to compare results when using helium and hydrogen carrier and buffer gas. As well as comparing the two gases, the group also assessed a number of ion volumes with different orifice diameters to look at their effect on sensitivity with either gas. With hydrogen increasingly being used as an alternative to helium for a number of GC analyses, this application demonstrates the analysis of DOA and energetic materials by GC-MS.
