Markes International will demonstrate its thermal-desorption systems at Pittcon 2010, to take place in Orlando from 29 February - 5 March.
Markes will display its TD-100 system, a universal analytical thermal-desorption platform for up to 100 RFID-tagged or untagged tubes.
Harnessing the field-proven and leading-edge TD technology for which the company is renowned, TD-100 incorporates sample re-collection for repeat analysis, cryogen-free operation for reduced running costs, tag read/write capability for enhanced tube/sample tracking and compatibility with the widest possible range of TD applications.
The TD-100 appeals to high-throughput laboratories involved in air monitoring (ambient, indoor or workplace), testing chemical emission levels from products (for example compliance with construction product regulations or Reach), flavour and fragrance profiling, fugitive emissions testing, quality control of residual solvents, CW agent detection and forensic analysis.
Both vapour-phase and material samples (solids, liquids, resins and emulsions) can be accommodated and compatible target analytes include ultra-lights, semi-volatiles and reactive species - at trace or high-level concentrations.
Markes will also highlight its micro-chamber/thermal extractor (u-CTE) technology.
Recent regulatory developments, primarily impacting construction-product sectors, require chemical emissions from products to be screened as part of routine quality control.
Markes' Micro-Chamber technology provides service labs and the manufacturing industry with a fast and cost-effective tool for screening chemical emissions in compliance with new regulations.
The latest unit complements Markes' range of chemical-emissions monitoring technology and allows four samples (each up to 100ml volume) to be evaluated simultaneously at temperatures up to 250C.
Bulk or surface-only emissions of VOC and SVOC, including key phthalate plasticisers, can be sampled from a variety of materials, including construction products, semiconductor/PC components, car trim, carpets, paints, textiles and children's toys.
The u-CTE is usually used in combination with sorbent tubes and offline TD-GC/MS.
Additionally, Markes' Micro-Chamber units are compatible with DNPH cartridges for formaldehyde emissions screening by HPLC.
The Markes International booth will also feature an innovative applications gallery, showcasing the breadth of areas that benefit from the company's unique technology portfolio.
The gallery will highlight Markes' solutions for a range of fields, including materials emissions, environmental analysis, defence and food, flavour and fragrance.
