Alternatives to Helium as a Carrier Gas for Simulated Distillation (SIMDIS)

Helium has long been the standard for most gas chromatographic methods due to its performance, safety, and suitability with Mass Spectrometry. Therefore, numerous methods have been developed using Helium as a carrier gas. In recent years, helium markets have become increasingly strained creating significant problems for laboratories using it, including:

However, since these analyses are critical to labs, we must consider alternatives. In a study by PAC, Nitrogen and Hydrogen were evaluated as alternatives for Helium for use in Simulated Distillation (SIMDIS), in particular ASTM methods D2887, D7500 and D7213. Data for Nitrogen is presented for peak resolution and peak skew, while also being compared with current method requirements. New method parameters are proposed for the methods mentioned based on the use of an alternative carrier gas.
