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.
