GC-FID Insights

What is GC-FID?

GC-FID stands for Gas Chromatography-Flame Ionization Detector. It is a highly sensitive and widely used technique for separating and quantifying volatile organic compounds. Gas chromatography separates compounds based on their boiling points, and the flame ionization detector detects these separated compounds by ionizing them in a hydrogen flame, creating ions that generate a measurable current proportional to the compound's concentration.

GC-FID Competitor Technologies

HPLC-UV

HPLC-UV is a liquid chromatography technique coupled with a UV detector. HPLC is used for compounds that are not volatile or thermally stable, which are better suited for GC-FID.
