Hydrogen as an alternative to Helium for gas chromatography

The choice of carrier gas depends on the type of gas chromatography (GC) detector that is used and the components that are to be determined. In general carrier gases for gas chromatographs must be of high purity and chemically inert towards the sample. Many gas chromatographers are considering hydrogen carrier gas instead of helium or nitrogen, but they might hesitate to do so because they have questions about performance, safety and cost.
This guide presents the basic steps to safely convert from helium to hydrogen as a carrier gas for gas chromatography. It presents useful data to estimate costs and demonstrates the excellent separation performance of hydrogen
