FAMEs Analysis Method Revalidation from Helium to Hydrogen for GC
10 Dec 2014

Many labs use helium carrier gas for their GC analysis of FAMEs, but as prices continue to rise, changing carrier supply to hydrogen supplied by a gas generator is becoming more attractive to many analysts. This article shows that it is possible to revalidate your method by keeping the linear velocity of hydrogen the same as that of helium. By adopting this approach, you can a column with the same dimensions and will only need to make slight adjustments to the GC method.
