Automated Re-collection with Single Thermal Desorption (TD) Autosampler

Nov 28 2006

In April of this year Markes International Ltd announced that its application for a UK patent on automated re-collection for thermal desorption using a single TD autosampler had 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. This is implemented on Markes new ULTRA 50:50 system which offers automated thermal desorption and sample re-collection for up to 100 tubes.

Granting of this patent confirms Markes position as the world's premier provider of innovative, high-performance concentration and thermal desorption technology. Other innovative TD systems from Markes International include the twin-trap TT24-7 for continuous on-line monitoring of trace organics in air.
Markes TD systems are in use in key industrial, regulatory and research labs 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.
