The analysis of adsorbent tubes can be a nightmare for analytical laboratories, especially when there is a requirement to get results on 100% of the tubes tested. Instrument problems, unexpected analyte loading outside of the GCMS calibrated range, and cross-contamination make the normal “one-shot” analysis very risky. Even attempting to recover a “split” fraction of the tube sample onto another tube is plagued with problems such as added background, poor leak-free validation, and incomplete recoveries from yet a second tube.
