PerkinElmer Awarded U.S. Patent on Method to Ensure Accuracy of Automated Thermal Desorption Gas Chromatography

Oct 15 2009

PerkinElmer announce that the U.S. Patent & Trademark Office (USPTO) has awarded it Patent No. 7,422,625 B2 covering an advanced method in gas chromatography (GC). The patent, titled “Methods and Systems for
Characterizing a Sorbent Tube,” protects the Company’s-proprietary methods that help gas chromatographers increase the accuracy of their results when using automated thermal desorption (ATD) gas chromatography (GC).

PerkinElmer’s automatic verification method described in the patent is deployed in the Company’s TurboMatrix™Thermal Desorber product line of GC systems to help users avoid manual errors in ATD measurement, which can cause inconsistent results and compromise sample integrity. The method was co-invented by Andrew Tipler, senior scientist, gas chromatography, PerkinElmer, and Neil Plant, senior scientist, Health and Safety Laboratory , Buxton, United Kingdom.

PerkinElmer Awarded U.S. Patent on Method to Ensure Accuracy of Automated Thermal Desorption Gas Chromatography “In the past, analysts had to be concerned that their results could be affected by lack of integrity of the packing materials in ATD tubes and traps,” said Tipler. “Our automatic method for checking the packaging integrity helps our customers maintain a high level of confidence in their analytical results, ultimately helping them to save time and increase lab productivity. The method is already incorporated in our TurboMatrix Thermal Desorber line, which can be used in a wide range of industries and applications.”

PerkinElmer first introduced ATD in 1982 as an effective method for isolating volatile compounds from various gaseous matrices so they can be introduced as samples into a GC instrument. It is the most popular technique for both indoor and outdoor air monitoring and is also used for analysis of soil, water, biofuels, polymers, packaging materials, flavors and fragrances, cosmetics, pharmaceuticals, and many other applications.
