ABSTRACT
As helium supplies become scarcer and more expensive, laboratories have been seeking sustainable alternative gas options. Hydrogen is a low-cost, renewable gas suitable for multiple Gas Chromatograph (GC)/Mass Spectrometer (MS) (GC/MS) applications. Similarly, Nitrogen can be a replacement as an alternative purge gas for VOC trap concentration. Both gases have generator options, thus lowering cost in both use and storage. The Agilent HydroInert source is a GC/MS ion source that improves chromatographic performance when using hydrogen as carrier gas. Its inertness minimizes hydrogenation and dichlorination reactions in the MS source, avoiding loss of sensitivity and spectral anomalies while offering a high-boiler peak shape. This is an analysis of Hydrogen carrier gas for the quantitation of volatile organic compounds (VOCs) with routine waste analytical method, U.S. EPA Method 8260, and preparation methods 5030/5035. For this study, the Teledyne Tekmar Atomx XYZ Purge and Trap (P&T) system paired with an Agilent 7890B GC and 5977B MS using the HydroInert source for the evaluation of Hydrogen carrier gas and Nitrogen purge gas as applied to the method and its required performance criteria.
