Simultaneous Analysis of 66 Pesticides by GC-MS Using Hydrogen Carrier Gas

Helium gas is typically used as a carrier gas for GC-MS. However, in recent years, the insufficient supply of helium gas and its increase in price have caused problems, prompting global efforts to address these problems. The use of hydrogen gas as an alternative carrier gas holds promise for addressing the issue. This application note presents the application of hydrogen carrier gas to the simultaneous analysis of a standard sample of 66 pesticides using the GCMS-QP2010 Ultra, which features a Dual Inlet Turbo Molecular Pump.
