'The Micro-Chamber / Thermal Extractors are effective small scale devices for the quality control of formaldehyde and (S)VOC emissions from a whole host of products and materials' said Dr Peter Hughes, product manager for the ?-CTE, Markes International. 'They allow companies to screen products for chemical emission levels in-house and with fast turn around in a way that complements more lengthy reference tests by third party laboratories. This has proved to be a very popular approach with users of the existing Micro-Chamber / Thermal Extractor.'
The new instrument complements the Markes range of chemical emissions monitoring technology and allows four samples (each up to 100 ml volume) to be evaluated simultaneously at temperatures up to 250°C. Bulk or surface-only emissions of (S)VOC, including key phthalate plasticisers, can be sampled from a whole variety of materials including construction products, semi-conductor/PC components, car trim, carpets, paints, textiles and children's toys. The ?-CTE is usually used in combination with sorbent tubes and offline thermal desorption (TD)-GC/MS. Additionally, Markes ?-CTE units are compatible with DNPH cartridges for formaldehyde emissions screening by HPLC.
New legislation such as REACH (Registration, Evaluation and Authorisation of Chemicals), Californian green chemistry initiatives (AB 1879 & the CARB formaldehyde rule) and the EC Construction Products Directive/Regulation is driving industry to monitor the release of (S)VOC from its products. These new regulations require products and materials to be sent to independent test laboratories for certification of chemical release and additional quality control of chemical emissions. However, QC of chemical release from materials requires much faster and lower cost tests than the three- and 28-day reference methods used for product certification; the Micro-Chamber / Thermal Extractors are particularly useful for in-house QC/screening of chemical emissions levels.
Markes International provides an innovative range of instrumentation, accessories and consumables for enhancing trace GC/MS analysis. Products include: thermal desorption (TD) instruments, headspace (HS)-TD technology and a broad portfolio of sampling accessories covering air sampling, materials emissions testing, breath sampling, soil gas analysis and direct desorption of volatiles from materials.
