Fast and flexible sampling of chemical and odours released from materials and food. Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a practical tool for rapid emission screening in R&D or as part of routine factory production control. It can be used to check surface or bulk emission profiles and to assess raw materials and compare products across a range. Applications include construction materials, car trim, consumer products and profiling volatiles released from foods and fragranced products.

4 inert micro-scale chambers (114 mL)- temperatures < 250 degree C- with toggle valves for gas isolation.

TD100-xr™ is an automated thermal desorption system for the rapid and unattended processing of up to 100 × 3½-inch sorbent tubes in a single sequence. It’s the perfect thermal desorption unit for high-throughput analytical laboratories needing to process large numbers of tube-based samples automatically.

UNITY–ULTRA-xr™ is an automated thermal desorption system for the rapid and unattended sampling of up to 100 sorbent tubes in a single sequence. Additional options include autosamplers for canister, bag or on-line analysis. The UNITY–ULTRA-xr is the ideal platform for labs requiring the flexibility to expand their capabilities to extended analyte ranges and varied sample types while maximising sample throughput.

UNITY–ULTRA-xr Pro™ is our highest capacity, automated thermal desorption system for the unattended sampling of up to 199 sample tubes in a single sequence. Its automated re-collection of tube and trap desorption split flows is unique to Markes and provides the most comprehensive re-collection options and enhanced sample security. It is ideal for laboratories needing to rapidly process large numbers of tube-based samples and take full advantage of the options for sample re-collection and automated re-analysis.

UNITY-xr™ is an industry-leading analytical TD instrument that provides exceptional performance for VOCs and SVOCs collected onto 3½-inch sorbent tubes, while offering unmatched upgrade flexibility for tube, canister and on-line automation. It’s perfect for laboratories with low throughput requirements that are starting out in TD, or for analysts needing a versatile thermal desorber for all their TD applications (whether tubes, canisters, or on-line).

Automated thermal desorption for 4½" sorbent tube analysis. Markes’ new TD100-xr DAAMS and UNITY–ULTRA-xr™ DAAMS systems are high-throughput, automated thermal desorption instruments for streamlined analysis of 4½″ Depot Area Air Monitoring Systems (DAAMS) tubes. Markes’ TD100-xr DAAMS and UNITY–ULTRA-xr™ DAAMS are ideal for laboratories needing to analyse chemical agents for homeland security applications using 4½″ tubes, with versatile upgrade options, including for regular 3½″ tubes. The new DAAMS systems are based on Markes’ tried-and-tested ‘xr’ systems, which include the latest generation of cryogen-free trapping technology.

Powered by best-in-class robotic automation, and using a modular design, Centri^® gives unrivalled flexibility for unattended, rapid and efficient extraction and enrichment of VOCs and SVOCs. With its four sampling modes, Centri offers maximum versatility for liquid, solid and gaseous samples. Innovation lies at the heart of Centri. Incorporating Markes’ advanced cryogen-free focusing trap technology, Centri optimises analytical sensitivity, and enhances the quality of information obtained from GC–MS.
Whichever major brand of GC–MS you’re using, the Centri sample extraction & enrichment platform lets you Discover more and Deliver more.

UNITY–Air Server-xr™ is an air monitoring system that introduces a controlled flow of sample directly into an integral focusing trap, allowing automated on-line analysis of VVOCs and VOCs in air or gas. It’s ideal for round-the-clock air monitoring of volatiles such as PAMS ozone precursors and odorous species, especially in remote locations where unattended sampling at time specific intervals is necessary.

UNITY–CIA Advantage-xr™ is an inert, multi-channel system for the automated analysis of VOCs in canisters and bags. It has capacity for up to 27 channels, operates completely without cryogen, and is also compatible with on-line and tube-based sampling. It’s the ultimate system for high-throughput laboratories running the canister-based methods US EPA TO-15/TO-15A and Chinese EPA HJ 759. It is also ideal for analysts needing a versatile TD system able to handle other whole-air samples, as well as sorbent tubes.

Advanced thermal desorber for uninterrupted monitoring of trace chemical vapours. TT24-7™ is a thermal desorption unit for continuous near-real-time (NRT) monitoring of VOCs and VVOCs 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, and operates completely cryogen-free. It’s an ideal TD system for those needing to continuously monitor air or gas streams for trace-level organic compounds by GC, such as chemical warfare agents. Importantly, its rapid response to changes in airborne concentrations allows the risk of exposure to hazardous chemicals to be minimised.
