Tue, Aug 9, 2022 11:00 AM EDT In this webinar, we explain how to analyse a wide range of volatile organic impurities from hydrogen fuel in a single run using “hydrogen-certified” thermal desorption with GC–MS and specific detectors ( SCD), complying with relevant global standards. Thanks to optimised preconcentration technology, the technique has proven to be more sensitive than alternative techniques and systems, while the ability to run both on-line and off-line samples gives ultimate flexibility to the analyst.

Identification of impurities in hydrogen fuel supplies was demonstrated using an on-line thermal desorption–GC–MS system, which complied with various standard methods.

Using high-capacity sorptive extraction with TD–GC–MS analysis for flavour profiling of cider and potato chips, contrasting unflavoured and flavoured-added products

Sampling and analysis of a challenging range of trace-level volatile & semi-volatile vapours of per- & polyfluorinated alkyl substances (PFAS) in air using TD–GC–MS

Using sorptive extraction to extract aroma compounds from honey, with automated statistical analysis to uncover differences and determine markers of authenticity

Demonstrating how a Markes Multi-Gas TD can operate with hydrogen carrier gas as well as it does with helium to meet all the criteria cited in US EPA Method TO-17
