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 .

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
