As we enter an era where the Environmental, Social, and Governance (ESG) aspects of how a company does business have never been more important, it is of the utmost importance to ensure the analytical methods used to produce data are as in tune with ESG principles and as cost effective as possible. Over the last decade it’s become more difficult for laboratories to use helium as it has become cost prohibitive along with it being an environmental hinderance to mine as it is a non-renewable resource. As most analytical methods on GCs with a FID or TCD detector have historically been run using helium as the carrier gas, this presented a challenge when trying to align and be ESG friendly. A total of 15 analytical methods were developed, optimized, and validated to use hydrogen as the carrier gas. During this development/optimization/validation phase special care was also taken to improve the efficiency of each method’s runtime. A comparison study was also performed between the helium and hydrogen methods to ensure the data was similar throughout the range of the calibration curve for all matrix types tested with a result of tremendous agreeance. This change over to hydrogen resulted in the elimination of helium from the laboratory’s FID and TCD methods which produced a yearly six figure cost savings, decreased our GC instrument run time, and greatly reduced our dependance on helium.
