Don't know what thin air is, but I would be delighted to see the results of a gas chrom/mass spec. Should tell us way more than we need to know.
For thin layer, see: https://en.wikipedia.org/wiki/Thin-layer_chromatography
GC works great for determining compounds present and quantity, but it may impact some results in the fact that it requires the sample to be a vapor... decarboxylation changes percentages from the original ratios.
