Gas Chromatography – A new book from Elsevier Proficiency testing – WASP scheme

Gas ChromatographyA new book, Gas Chromatography, edited by Colin Poole has been published by Elsevier (ISBN: 978-0-12-385540-4). This contains a chapter entitled ‘Thermal desorption for gas chromatography’ written by Markes’ Director, Elizabeth Woolfenden.

The hardback book, which contains 31 chapters over 688 pages, is a single source of authoritative information on all aspects of the practice of modern gas chromatography, from its development right through to its use in space exploration.

As part of our service to customers, Markes likes to make TD users aware of complementary third-party services that could be of interest and benefit. Proficiency testing (PT) schemes are a case in point.

One of the most popular PT schemes for thermal desorption is the Workplace Analysis Scheme for Proficiency (WASP). This tests the performance of laboratories measuring exposure to hazardous chemical substances in the ambient, indoor and workplace air environments using TD methods.

The scheme was established in 1988, and currently has more than 200 laboratory participants worldwide.

HSL LogoThe WASP scheme is operated by the UK Health & Safety Laboratory, which oversees management, registration and membership, together with preparation and distribution of the spiked tubes, processing the participant data and providing reports.

Please contact Markes for further details if this is of interest to you.
