Founded by Prof Peter B Stockwell in 1983, PSA has gained an international reputation as leaders in the determination of these environmentally important elements. Matrices include water, soils, sludges, effluents and gases with customers and installations worldwide. The company's initial focus was supplying accessories for automating and improving the detection limits of Atomic Absorption, Inductively Coupled and Direct Current Plasma spectrometry detection systems. Products included Hydride/Vapour Generators, Autosamplers and Valve Switching Units. In 1987/88 PSA developed and launched the Merlin Plus system for ultra-low level mercury determinations. With this new analysis system PSA developed a product line to parallel the existing OEM related business and began to provide complete analytical systems to solve customer problems. Using the Atomic Fluorescence technique, the Merlin Plus system gave analysts the ability to measure mercury at levels of below 1 ppt at up to 120 samples per hour. Please visit our "Elements of Interest" pages on the following elements: Mercury, Arsenic, Selenium, Antimony, Bismuth and Tellurium.
