Model TD-100 Series - Automated Thermal Desorber

Automated thermal desorber for high-throughput processing of sorbent tubes. TD-100™ 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, TD-100 quantitatively re-collects the thermally desorbed sample for re-analysis or storage, enhancing sample security. TD-100 also features an ...

Model TT24-7 Series - Advanced Thermal Desorption System

Uninterrupted monitoring of trace chemical vapours. TT24-7™ is an advanced thermal desorption system for continuous near-real-time (NRT) monitoring of VOCs and SVOCs in air or gas. TT24-7 ensures 100% data capture by using a twin-trapping design that can accommodate a wide range of sampling flow rates. As with all Markes’ thermal desorption instruments, TT24-7 operates completely cryogen-free, enabling it to be used in ...
