automated thermal desorption-gas chromatography mass spectrometry https://orcid.org/0000-0001-5985-7429 ATD, GC/MS automated thermodesorption-gas chromatography mass spectrometry automated thermal desorption gas chromatography mass spectrometry ATD-GC/MS ATD-GC-MS A method where a sample mixture is first adsorbed onto packed tubes (e.g. Tenax) then each tube is automatically moved into a desorption oven and heated (100–280 °C for 5–20 min) to promote thermal desorption of the mixture into the headspace of the tube. The headspace is sampled and used for gas chromatography and the eluent is then ionised and characterised according to mass-to-charge ratio and relative abundance.
