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.

 

Product benefits

  • Reliable, trace-level detection – TT24-7 delivers unparalleled sensitivity and selectivity, even in dirty environments. It eliminates false negatives and minimises false positives.
     
  • Get your results in near-real-time with fast cycle times.

  • Rest assured that the continuous monitoring provides 100% data capture – no blind spots.

  • Convenience – cryogen-free operation makes the system suitable for static and mobile laboratories.

  • Flexibility – the cryogen-free design makes TT24-7 suitable for use in either static or mobile laboratories.

  • Peace-of-mind – you are buying a quality product from the recognised leader in thermal desorption instrumentation.

Features

  • Highly time-resolved data – Cycle times as low as 3–5 minutes.

  • Dual-trap continuous monitoring – 100% data capture.

  • High sensitivity and wide range of sampling flows (up to 800 mL/min) with quantitative trapping.

  • Inert, uniformly-heated flow path offers compatibility for C2–C40 compounds and reactive species.

  • Split and re-collect samples on to sorbent tubes for backup or re-analysis.

  • Efficient desorption means no cross-contamination, and improves chromatographic resolution, minimising false positives. 
     
  • Small footprint – Suitable for mobile laboratories.
     
  • Operates cryogen-free – Ideal for unattended remote-site operation over extended periods.
     
  • Compatible with any make of GC and fast GC.

 

Key applications

 

  • Defence and homeland security.
     
  • Environmental and workplace air monitoring.
     
  • Cleanroom air monitoring

  • Monitoring of odour and fragrance profiles.
