July 2007 New Product Annoucement: Enhanced analysis of ‘Air Toxic’ VOCs in canisters following US EPA methodsASIS 8 Building on the success of Air Server for automated on-line sampling of air / gas streams, the new ASIS 8 module from Markes International connects to the company’s UNITY or ULTRA-UNITY thermal desorption (TD) systems to provide enhanced, cryogen-free and automated analysis of VOCs in canisters, Tedlar™ bags and other whole air/gas containers. The ASIS 8 comprises thermostatted, 8-channel stream selection hardware complete with inert sample flow path and an internal standard addition facility. This complies with US EPA Method TO-15 for monitoring volatile organic Air Toxics in ambient air using canisters. Featuring cryogen-free operation combined with unbeatable chromatographic performance, UNITY-ASIS 8 systems allow sequential analysis of up to 8 canisters. The new technology provides best possible detection limits for trace-level vapour-phase organics while significantly reducing laboratory running costs by removing the expense and downtime associated with liquid cryogen ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~June 2007 New Product Announcement: RFID-tagging technology to revolutionise sorbent tube tracking and identificationTubeTAG™ Sorbent tube informaticsTubeTAG is a patented, powerful and unique tool for tracking thermal desorption tubes used for air monitoring and other applications. The product consists of RFID tag assemblies for attaching onto individual sorbent tubes, a tag reader / writer (TAGSCRIBE) and software."We have a lot of sorbent tubes lying around our lab. Before TubeTAG there was no fool-proof way of being able to track these tubes; knowing what sorbent was in each, the history of each tube, and so on...TubeTAG has revolutionised the way we work"~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~May 2007 Two of the most powerful GC introduction techniques, headspace (HS) and thermal desorption (TD), brought together in a new systemDesigned to integrate with either the 70-position G1888 HS system or the 44-position G1290 (7694) HS system from Agilent Technologies, Markes HS-TD system opens up new possibilities to users who require enhanced sensitivity for HS applications and/or require a versatile sample introduction system capable of dealing with any matrix; soil, water or air; solid, liquid or gas. The HS-TD incorporates Markes UNITY thermal desorber, with its market leading trapping technology and pioneering quantitative sample re-collection facility. UNITY is fully compliant with all standard TD methods. The combined system offers three modes of operation:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~January 2007 Markes Micro-Chamber shows good quantitative and qualitative correlation with conventional emission test methods Analytical Bioanalytical Chemistry, 2007. A microscale device for measuring emissions from materials for indoor useT Schripp, B Nachtwey, J Toelke, T Salthammer, E Uhde, M Wensing, M Bahadir The paper details work undertaken by the Fraunhofer Wilhelm-Klauditz-Institute, Germany in conjunction with the University of Technology, Braunschweig, Germany evaluating the Markes µ-CTE in comparison to conventional emission test methods. "Good quantitative and qualitative correlation was obtained for measurements at ambient temperature. Moverover, it was shown that ambient-temperature emissions data collected using the µ-CTE as rapidly as possible ... provided a reliable guide as to how well that material would perform in subsequent 3-day chamber tests of VOC emissions." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~January 2007 Markes International announces TD trade in programme Markes International is offering an unmissable trade in programme for old or discontinued thermal desorption (TD) systems, for a limited period only. TD users trading in their old systems for a new 100-tube automated TD from any authorized distributor of Markes TD technology will qualify for a half price offer on Markes own-manufactured TD accessories and consumables worth up to US$20,000. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~11 September 2006Markes Instrumentation makes Headline News in FranceFrench TV station, TF1, reports that Markes International Ltd. TD instruments are being used by the French authorities in mobile laboratories for depolyment at potential chemical attack incidents.Un camion pour contrer les risques terroristesEn cas d'attaque chimique ou bactériologique, la gendarmerie dispose désormais d'un laboratoire mobile.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~3 August 2006 Thermal Desorption (TD) Application Guides Markes International - the world’s leading supplier of TD equipment – has published a series of four new booklets showing the benefits of thermal desorption for real-world GC(MS) applications in: I. Air Monitoring II. Residual Volatiles & Materials Emissions Testing III. Defence / Forensic IV. Food, Flavour, Fragrance These are available free-of-charge from Markes. Please see press releases for more detailed information.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~5 April 2006Automated re-collection with single thermal desorption (TD) autosampler – Patent granted to Markes International Markes International is proud to announce that its application for a UK patent on automated re-collection for thermal desorption using a single TD autosampler has been granted. The new patent has a priority date of 13/11/02 and is reference number GB2395785. Pioneered by Markes International Limited in 1998, quantitative re-collection of TD samples (SecureTD-Q) has set a new benchmark for analytical thermal desorption technology. SecureTD-Q allows repeat analysis and validation of TD methods / data as referenced in international standard methods such as ASTM D 6196-03. The new Markes patent covers both automated re-collection onto clean, conditioned tubes and re-collection back onto the original sample tube using the same TD autosampler. Granting of this patent confirms Markes position as the world’s premier provider of innovative, high-performance concentration and thermal desorption technology. Markes systems are in use in key industrial, regulatory and research laboratories around the globe. Key applications include: air monitoring for environmental health and safety, monitoring trace level chemical warfare agents for defence and counter terrorism, food / flavour / fragrance profiling and materials quality control – including emissions testing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~20 Feb 2006New headquarters for worlds leading supplier of thermal desorption equipment As part of its continued expansion Markes International Ltd. is pleased to announce a move to brand new premises on the Gwaun Elai Medi Science Campus in Llantrisant, South Wales.
