New Products
Markes has introduced several new products recently including:

TT24-7 Continuous Air / Gas Monitoring System	΅-CTE Micro-Chamber / Thermal Extractor	MTS-32 Sequential Sampler
This state-of-the art thermal desorption system incorporates two electrically-cooled traps which operate in tandem to ensure 100% data capture. The acute toxicity of many organic vapours means that near real-time (NRT) data is sometimes required to minimise the risk to human health. Chemical processing plants and government / military establishments are key examples of sites which may require such round-the-clock operation. Continuous monitoring may also be required for general kinetic studies i.e. monitoring changes in odour profile over time. Applications in this case range from atmospheric chemistry and biological research to food, flavour and fragrance profiling.	A versatile and automated tool for testing odours and emissions from materials at ambient or elevated temperatures. The ΅-CTE system comprises six micro-chambers which allow surface or bulk emissions to be tested from up to six samples simultaneously. The ΅-CTE is compatible with industry standard sorbent tubes. Adaptors are also available for non-standard 6 mm O.D. sorbent tubes and aldehyde (DNPH) cartridges with 4 mm O.D. ends.	For unattended sequential sampling onto a series of sorbent tubes. The MTS-32 allows air to be pulled, sequentially, through a series of up to 32 industry standard sorbent tubes using constant flow pump technology. The constant flow pump ensures that the same flow rate and volume of air is sampled onto each tube in the sequence regardless of impedance variations. Sampling times (1 minute - 99 hours) and flows (5-100 ml/min) may be user selected.

New Applications
Several new Thermal Desorption Technical Support Notes have been published and these are available to download from the website, following registration:

Exhibitions and Conferences

NBC International Conference and Exhibition Markes International will be exhibiting at The First Annual NBC International Conference & Exhibition, October 17-18, 2005. Brussels, Belgium - www.smi-online.co.uk/nbcint1.asp NBC International, the world's most widely read and respected CBRN magazine in partnership with SMI Conferences will host the most important NBC/CBRN event of 2005. Speakers are from Singapore, US, Italy, Switzerland, Sweden, France, UK and Germany, and represent an equitable split between civil and military. The NBC International conference is seeking to share the lessons that are being learnt in both these communities, from the streets of Baghdad to Berlin, and to prepare a stronger defence against non-conventional weapons. For further information please contact CWmonitoring@markes.com

The 10th International Conference on Indoor Air Quality and Climate – Indoor Air 2005 Markes International will be presenting three scientific papers at this prestigious conference which is to be held this year in Beijing, China, September 4-9, 2005 - http://www.indoorair2005.org.cn/index.asp The application of thermal desorption for the analysis of trace toxic compounds in areas of human occupation Improving the determination of VOCs and semi-VOCs in building materials and car trim components using direct thermal desorption Comparing emission cells to small chambers for materials emissions testing For further information please contact enquiries@markes.com

Symposium Materials Emissions Testing – An Update for Industry A highly successful symposium was co-hosted in June 2005 by Markes International and BRE (the UKs leading independent laboratory in the field of materials emissions testing and indoor air quality monitoring). On-going regulatory developments such as the EU Construction Products Directive and new health-based evaluation protocols are putting additional pressure on construction product and furnishing manufacturers to test emissions as part of routine QA/QC. The objective of the symposium was to present manufacturing industry with a comprehensive update on relevant regulations and standard test protocols from people at the front line of method development. Experts from industry and leading commercial laboratories also reviewed practical aspects of certification testing and recent developments for rapid in-house emissions screening. The proceedings of this symposium are available to anyone who was unable to attend – for further information please contact enquiries@markes.com
