Evaluation of Alternative Carrier Gas for US EPA Method 524.3

Due to the shortages and increased cost of helium, the preferred carrier gas in gas chromatography, alternative carrier gas options are in ever increasing demand. This application note describes a study in which the Teledyne Tekmar Atomx Multimatrix Autosampler was evaluated in conjunction with a Thermo Scientific TRACE 1310 / ISQ GC/MS, while employing hydrogen carrier gas and nitrogen purge gas to perform USEPA Method 524.3.
