Applying H₂ Carrier Gas to Real-World GC-MS Analyses

With increased price and pressure on the helium (He) market, laboratories are looking for a more sustainable alternative to helium and exploring the option of hydrogen (H₂) carrier gas, which can be generated in the lab in a cost-effective manner and produces fast chromatography and higher sample throughput.

As hydrogen is a reactive gas, hydrogenation and dechlorination reactions can occur in the mass spectrometer electron ionization (EI) source. These reactions which make applying hydrogen carrier gas to many applications difficult.

• Help improve performance of H₂ carrier gas for GC-MS and GC-MS/MS analyses acquisition mode separately
• Retain mass spectral fidelity
• Allow users to continue using existing helium-based mass spectral libraries
