Abstract:
The current crisis surrounding the helium gas supply is making laboratory operations unsustainable from both economic and throughput standpoints. Whereas reduction of the helium consumption is a logical first step, some laboratories face challenges to obtain any helium supply. Hydrogen in turn, is a more cost efficient alternative and can be even generated directly in the lab. However, switching to hydrogen as carrier gas often means a change in performance usually requires re-optimization of the method. In this poster, the use of hydrogen for the analysis of polyaromatic hydrocarbons (PAHs) and selected pesticides will be shown to illustrate how reliable and efficient analysis can nonetheless be obtained.
