The operational considerations for switching from helium to hydrogen …
The operational considerations for switching from helium to hydrogen
are explained and options discussed. Analysts need to make decisions
about their approach to switching the carrier gas to hydrogen. Are they
looking for analysis time reductions or would they like to quickly switch
their analysis without having to optimize or change their run conditions?
The source of the hydrogen and purity levels needed for its use as a
carrier gas are discussed along with the advantages or disadvantages of
using hydrogen generators versus gas cylinders.
