Markes TD-100 thermal desorption system (Refurbished)

The Markes TD-100™ is a high-throughput, fully automated thermal desorption system, designed to process up to 100 sample sorbent tubes in a single sequence.

It offers unparalleled efficiency and precision for laboratories analyzing volatile and semi-volatile organic compounds (VOCs and SVOCs). With its advanced features like robust automation, stringent leak testing, and customizable desorption options, the TD-100 ensures reliability and sensitivity for trace-level analyses.

The system's compatibility with wide-ranging volatility profiles and its innovative sample re-collection capabilities make it an ideal solution for high-demand applications, including environmental monitoring, industrial hygiene, and chemical research.

Technical Specifications of the Markes TD-100™

System Features
