Advances in ultra-trace air toxics analysis: Cryogen-free canister pre-concentration and GC–MS for US EPA Method TO-15A
Application Note 169

How to optimise your PFAS air sampling method using thermal desorption
Webinar discussing the advantages that TD offers, how to optimise a system for targeted and untargeted PFAS analysis, and how to overcome challenges posed by low-level PFAS monitoring.

Indoor Air Quality – The science and regulations behind the headlines
Addressing the wide range of regulatory and market pressures placed on manufacturers to limit the chemical emissions from products and materials. This webinar highlights using TD–GC–MS to characterise the chemicals that affect indoor air quality. It highlights the importance of robust sample preparation, sampling and analytical procedures.

Panel discussion – Should I move from helium to hydrogen carrier gas?
Should GC–MS analysts be making the switch to using hydrogen instead? This was the topic of a panel discussion, “Helium shortage 4.0: Is hydrogen carrier gas the solution to the GC–MS problem?” hosted by Separation Science, and held in September 2022. This blog post summarises the topics covered, and shows that there’s a lot to gain by moving to hydrogen.

How diffusion-locking technology cracked the problem of high-capacity thermal desorption automation
Blog post explaining a key technological advance in protecting sample integrity and its continued relevance for users of thermal desorption

Target and non-target approaches for quality and safety testing of foods and beverages
Learn how to overcome common problems associated with sampling volatiles from foods and beverages and explain how the sensitivity can be improved using trap-enabled, extraction and enrichment methods.

Assessing low-temperature thermal treatment techniques for PFAS using TD–GC–MS analysis
This on-demand webinar delves into the analysis PFAS – the “forever chemicals” that are known pose an ever-increasing risk in the environment – using automated TD–GC–MS

What is thermal desorption?
Thermal desorption (TD) is a versatile preconcentration technique for gas chromatography, which is used to analyse volatile and semi-volatile organic compounds from solids, liquids or gases.

Using hydrogen as a carrier gas with -xr series thermal desorbers
Markes International’s Multi-Gas enabled thermal desorption (TD) instruments have been selected for the prestigious Innovation Awards from The Analytical Scientist – the world’s first range of TD instruments that are independently safety-certified to run using helium, nitrogen or hydrogen as carrier gas in TD–GC–MS workflows.
“Moving from helium to hydrogen for TD makes economic sense, with helium prices increasing rapidly. Many labs who have become frustrated with helium availability will find this product to their liking.”
