Gas Chromatography Method List alternative to Helium

The list below shows methods which have been rewritten to use Hydrogen or Nitrogen carrier gas for GC as an alternative to Helium.

For methods which indicate that nitrogen gas or hyrdrogen gas can be used, a nitrogen generator or a hydrogen generator will be suitable for use.

Please note that customers using methods which need helium can also use Precision gas generators for detector or make-up gas.
