Markes TD – TT24-7




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 both static and mobile laboratory facilities.

Who uses the TT24-7?

TT24-7 is ideal for those needing to continuously monitor air or gas streams for trace-level organic compounds by GC. It allows the risk of exposure to hazardous chemicals to be minimised by responding rapidly to changes in airborne concentrations.
