Following an assessment by an independent body, P S Analytical has been awarded ISO 9001 certification.  This certification has only been achieved by about 5% of UK businesses and this prestigious award is supported by the Government and recognised worldwide.

Said a delighted Prof Peter Stockwell “We have always been proud of the service we offer our clients and the way that we conduct our business.  Now with the award of ISO 9001:2000 certification, this has been confirmed by outside experts who are used to judging standards on a daily basis in a wide variety of trades and industries”.

Danny Littlechild, who undertook the assessment for QMS Quality Management Systems, paid particular tribute to “the investment in people and training that enables P S Analytical to provide an efficient service to their customers”.

As part of its ongoing product development P S Analytical has also recently received the ATEX EC-Type certification permitting our online mercury measurement system for natural gas to be installed in Category 2 IIC T4 designated areas.  The procedure used for the measurement of mercury by atomic fluorescence basically follow the ASTM 6350-98 (1) and ISO 6978-2 (2) procedure and the PSA 10.670 is specifically configured for the petrochemical industry.  The system which has found widespread application is based upon the PSA Sir Galahad instrument and can be readily tailored to individual customer requirements specifically to handle natural gas and liquefied natural gas measurements.  P S Analytical’s expertise allows measurements to be made at various stages of the process and also enables the user to control mercury removal techniques to enable the plant to provide products within the low levels of mercury in the material and to achieve a better sales price of that product.

Systems have been installed worldwide since 2001 and these have been operated on a continuous basis using P S Analytical proprietary calibration devices to keep the instrumentation fully calibrated and minimising operator intervention with the system.

Where clients are unsure if they have a requirement for continuous online system the PSA 10.537 PLDS can be used to carry out preliminary tests on the Hg levels.  This system is suitable for use in hazardous areas and is the accepted industry standard for this type of measurement.
