Improving thermal desorption (TD) applications with sample re-collection
Instant Insight 005
Thermal desorption used to be seen as a ‘one-shot’ technique, with any sample split being lost to waste.
Quantitative sample re-collection overcomes this limitation, by directing the split flow onto a sorbent tube, enabling repeat analysis and sample archiving.
Many modern thermal desorption instruments allow some form of sample re‑collection capability, but only Markes offers full method-compliant functionality on every system.
In this Instant Insight, we explain the important requirements and features of TD sample re-collection, and highlight the analytical challenges it can address.
