How does an FID work?
An FID, or Flame Ionization Detector, is the most common detector paired with gas chromatography instruments for analytical applications. But how does and FID work? An FID uses a flame to ionize organic compounds containing carbon. Following separation of the sample in the GC column, each analyte passes through a flame, fuelled by hydrogen and zero air, which ionises the carbon atoms. ...
