Inverse GC

Inverse Gas Chromatography ( IGC ) is an analytical technique used to characterise materials like fibres and powders.

Basically it is a chromatographic technique, so gases (vapours) are flowed over solids in a tube and quantified with a FID .

igc vs gc


However it is the inverse of classic GC, so your solid sample is the stationary phase and vapours like decanes are flowed over the surfaces before the FID.

There is a more detailed explanation of IGC on the wikipedia website
