Enabling confident, high-throughput, automated TD analysis

TD100-xr™ is a high-throughput, automated thermal desorption system for the rapid and unattended processing of up to 100 sample sorbent tubes in a single sequence.

In contrast to other thermal desorption units, TD100-xr quantitatively re-collects samples for re-analysis or storage, enhancing sample security. TD100-xr also features an electrically cooled cold trap, dispensing with the expense and inconvenience of liquid cryogen.

Who uses the TD100-xr?

TD100-xr is perfect for high-throughput analytical laboratories needing to process large numbers of tube-based samples automatically.


Product benefits

  • Enhance throughput – capacity for up to 100 tubes and compatibility with the widest range of TD applications allow you to maximise productivity, e.g. unattended operation all weekend.

  • Peace of mind – with quantitative sample re-collection for repeat analysis, TD100-xr offers simple method/data validation and overcomes the ‘one-shot’ limitation of other systems.

  • Enhance productivity with the world’s most versatile thermal desorber – TD100-xr offers unmatched analytical performance for the widest range of TD applications.

  • Reduce running costs by avoiding the need for cryogen.

  • Security – tubes remain capped at all times, so avoiding sample contamination and/or analyte loss.

  • Reduce errors with the TubeTAG™ sample informatics system.

  • Be confident – you’re using a desorber that complies with key standards such as US EPA Method TO-17.


  • Automated, cryogen-free, unattended operation for up to 100 sample tubes.

  • Confidence in results through quantitative sample re-collection of split flows.

  • Inert sample paths and extended temperatures allow quantitative recovery of C2 to C44, including reactive and thermally labile species... from percent to sub-ppt concentrations.

  • Method compliance aided by leak-testing, water management and addition of internal standard.

  • Enhanced traceability of samples using barcodes and RFID TubeTAGs.

  • The short, heated transfer line allows TD100-xr to be installed on all major makes of GC and GC–MS.

  • High-precision parts result in increased robustness.
