5400B Thermal Transfer System

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 into another tube is plagued with problems such as added background, poor leak-free validation, and incomplete recoveries from yet a second tube.

The 5400B Thermal Transfer System simplifies the entire thermal desorption tube analysis process. The 5400B automates the precise transfer of tube samples into vacuum-tight Bottle-Vac samplers. During desorption, approximately 600cc of nitrogen is used to recover the tube sample much more completely than direct GC thermal desorbers – which attempt to desorb the sample using as little helium as possible.

The 5400B performs an automated leak check before thermally desorbing the tube sample to ensure quantitative sample recovery.After desorption, final pressure is adjusted to obtain the same desorption volume for each sample transfer. Once the sample is transferred into a Bottle-Vac, as little as 0.1–1.0cc of the sample can be analyzed, or the entire volume using a 7200 or 7200 / 7650. Further dilutions are also easily accomplished.
