The Determination of Mercury and P S Analytical - a Legendary Kinship a Legendary Kinship

From humble beginnings when it was founded in 1983, P S Analytical (PSA) now operates globally to resource all scientists who have an interest in the accurate determination of mercury and its compounds.

With focus comes success

PSA operates within very niche markets that primarily focus on the use of Atomic Fluorescence Spectrometry (AFS) as a means of detection.

Since its foundation over 30 years ago, PSA has focussed on the small number of analytes which can be usefully determined by AFS (Hg, As, Se, Sb and Bi) and utilises the remarkable power of AFS to obtain the most reliable and precise results for these elements. This is our core competency and a compelling combination that provides targeted and exceptional analytical performance.

A legendary triumvirate

Using collective knowledge and experience PSA has designed and developed iconic analysers such as the Merlin, Sir Galahad and the Excalibur systems. These systems continue to be held in high esteem for their performance, reliability, robustness, ease of operation and value. These attributes are all hallmarks of the PSA brand, however, our expertise does not stop with these analysers; all manner of sample handing accessories are available to handle/pre-treat and present a representative sample for analysis. Accessories and modules have been developed for high temperature and pressure process gases/liquids, particulate laden and wet stack gases, mixed phase petrochemical samples, LNG, LPG applications as well as separation and chromatographic solutions for speciation studies.

This holistic approach to the overall analysis has culminated in the design and roll out of our on-line range of analysers that are capable of conditioning the sample, self-calibration and cleaning and unattended operation for extended periods of time. On-line applications include LNG process streams, liquid hydrocarbons, continuous emission monitoring (e.g. from stacks) as well as waste water applications from a variety of industrial processes.

Consulting Services

PSA is often approached to offer independent Hg surveys and consultancy services to establish and verify results across the entire process and to explain the significance and potential impacts that Hg may have. We have a great deal of experience performing mass balance studies for natural gas processing plants, liquid extraction processing plants and petrochemical plants. Mercury occupational exposure studies and the deployment of mercury management plans are also be provided using our team of mercury experts. Our ever growing list of application notes are available.

Our equipment has been fully certified to operate in hazardous area locations. PSA is the only company to offer online systems for liquid hydrocarbons including unstabilised samples. PSA is able to provide a complete engineering solution including the analyser shelter, probes, sample lines, sampling conditioning systems and analyser. With multiple signal processing options interfacing to the DCS is made very easy. 

So whether you application is a simple drinking water laboratory based analysis or a more complex on-line application we’d love to hear from you.

PSA has regional offices in the UK, USA and Asia and with literally thousands of systems in the field today, and supporting networks in Europe, SA and SE Asia, offers the ideal package of performance, reliability and support.
