What Does AFID Stand For?

AFID stands for Alkali Flame Ionization Detector

The Alkali Flame Ionization Detector (AFID) is an analytical instrument used primarily in gas chromatography for detecting trace amounts of alkali metals. It operates by introducing a sample into a hydrogen flame, where alkali metal ions are formed and subsequently detected through ionization. The AFID offers high sensitivity and selectivity for alkali metals, making it an essential tool in applications such as environmental monitoring, petrochemical analysis, and food safety testing. Its ability to provide real-time measurements contributes to efficient and accurate analysis in various scientific and industrial fields.
