Ongoing helium shortages can cause unpredictability for gas chromatographers. Here, you’ll find resources and strategies for managing the price fluctuations and potential delivery interruptions associated with helium carrier gas.
To start, consider whether you really need to use helium as your carrier gas. Regulated methods, SOPs, or high-sensitivity GC/MS methods often require the use of helium. However, other methods may allow you to convert to hydrogen or nitrogen carrier gas as helium alternatives.
