Pros | Cons | |
---|---|---|
Helium Carrier Gas | Always the first choice, if available | Frequent shortages and delivery interruptions |
Excellent chromatographic and MS performance | Inconsistent or high costs | |
All reference spectra in libraries are obtained with helium | Sometimes difficult to find in chromatographic grades | |
Hydrogen Carrier Gas | Best alternative to helium | Requires attention to safety |
Better chromatographic resolution and speed compared to helium | Requires attention to reactivity | |
Nitrogen Carrier Gas | Inexpensive | Requires longer run times to achieve resolution |
Widely available in chromatographic grades | Not recommended for use with MSD | |
Safer than hydrogen |
