About Us
Since 1983 experts at PS Analytical have worked at the cutting edge of mercury analyzer technology, with a focus on automated low-level mercury analysis. The development of the innovative Merlin system, combining atomic fluorescence spectrometry (AFS) with vapour generation (VG) was the first step on a path which has led PSA to the forefront of technology.
PSA continues to invest in its research programme to provide total mercury analyzer solutions to the marketplace.
Systems provide the ability to carry out mercury speciation as well as offering total mercury determination... Read More...

Detecting Mercury in Seafood
Introduction There is a potential accumulation risk of methylmercury when large quantities of fish and seafood products are consumed on a regulator basis. For most populations fish is the main source of methylmercury in food. In general, concentrations are below 0.4μg/g, but fish at the highest trophic levels may contain methylmercury above 5μg/g. Older and larger [...]
Detecting Mercury in Natural Gas
Mercury can be present in natural gas from zero to quite high concentrations and may be found in different forms. Having the right mercury analyzer is vital to accurate measurement. Why measure Mercury in natural gas? Knowledge of the total mercury content of natural gas is extremely important for the following reasons: firstly mercury is [...]
Mercury Analyzer Calibration
All mercury analyzers need to be calibrated in order to ensure correct results. The method of calibration will depend on the type of instrument and the application. For atomic absorption and atomic fluorescence analyzers used for measuring mercury in liquids, the calibration is achieved by preparing a series of solutions containing concentrations of mercury which [...]
