Latest advances in GC/MS air analysis workflows: from PFAS to utilizing hydrogen carrier gas

Event overview

In the first half of this presentation, Hannah Calder will share how Markes’ thermal desorption (TD) equipment coupled to Agilent’s GC-MS systems can be used for PFAS analysis from air and materials. The presentation will examine how labs can take existing methodologies for air monitoring and materials testing to expand them to enable the analysis of new environmental contaminants – in this case PFAS. Analysis of PFAS in air and from materials is rapidly gaining
momentum with multiple standard methods for monitoring of gas phase species using GC-MS in development globally to complement LC methods already in place.

In the second half of this presentation, Markes’ Aaron Davies will discuss how labs can benefit from changing their pool of instruments across to hydrogen carrier gas. The example of US EPA method TO-15 will be used to highlight how the change to hydrogen and using HydroInert — an optimized source for hydrogen carrier gas — enables equivalent performance, a quicker turnaround time for sample analysis, and a significant cost saving. Both Markes Multi-Gas enabled TD instruments and Agilent GC/MS systems are certified safe for use with hydrogen carrier gas. When coupled with the new HydroInert source, mass spectral fidelity is retained and users can continue using existing helium based mass spectral libraries and quantitative methods.
