Eliminating lab dependency on helium as a carrier gas for TD–GC–MS
Presented at Pittcon 2023
Helium has long been the gas chromatographers’ carrier gas of choice. However, helium is becoming increasingly difficult to source and global prices are rising rapidly. Many laboratories are looking for a more sustainable alternative to helium and are exploring the option of hydrogen as a carrier gas to eliminate this dependency on helium for GC, GC–MS and thermal desorption (TD)–GC–MS.
This poster evaluates the benefits of using hydrogen over helium in gas chromatography, including cost, environmental friendliness, convenience, time-saving and performance. It demonstrates how Markes’ Multi-Gas enabled TD instruments can deliver automated sample preparation, preconcentration for sub-ppb level analysis and compliance with key environmental monitoring methods.
