P S Analytical is a leading company in the manufacture and supply of instrumentation for the analysis of Mercury (Hg), Arsenic (As), Selenium (Se), Antimony (Sb), Bismuth (Bi) and Tellurium (Te) in all matrices.

Systems generally utilize Atomic Fluorescence Spectroscopy which offers many advantages over other techniques (such as Atomic Absorption Spectroscopy) for the determination of mercury and the hydride forming elements including better sensitivity, selectivity and linearity.

Where regulations demand however systems for Mercury analysis based on Atomic Absorption Spectroscopy are still available.

The PSA systems are utilised for many diverse applications, and cover all sample types from gases to liquids and solids. For the analysis of total mercury and/or its speciation, the PSA systems offer unrivalled performance and reliability within the marketplace. In addition, this flexibility extends to the hydride forming elements mentioned above.

P S Analytical ongoing commitment to research and development enables the company to react quickly to customer needs and regulatory requirements with an exciting instrumental range.

Whether it’s in the supply of standard systems or to producing specialised systems tailored to user’s specific requirements, the results and sensitivity of our instrumentation has forged our place as company of choice in the field of analytical instrumentation.
