Keywords:
Place the sorbent or carrier tube in a compatible thermal desorption apparatus. As each tube in turn is sealed into the analytical flow path, system integrity should be checked to ensure there are no leaks which could lead to sample losses. Purge the air from each tube before heat is applied to avoid chromatographic artifacts arising from oxidation of the sorbent or damage to the chromatographic system. Heat the tube to displace the organic vapors which are pas
