Monitoring Mercury Levels in the Environment Utilising Both Laboratory and Process Instrumentation  

For over 25 years P S Analytical (UK) has been at the forefront of environmental monitoring, with particular emphasis on mercury determination and speciation. PSA has developed instrumentation for both laboratory and process applications backed up by an in-house team of experts, worldwide distributor network and on-going R&D programme. Our expertise spans the ability to determine mercury in gases, liquids and solids at ultra low levels. Mercury can be present in many forms and by coupling to chromatographic techniques, the PSA Merlin Instrument forms an ideal detector for mercury speciation studies, providing data required to define suitable removal strategies.

In the petrochemical industry mercury measurements are vital, since failure to detect the presence of mercury, even at low levels, has in the past led to catastrophic failures. PSA instrument routinely detects mercury levels at sub ppb levels over a wide range of matrices.

Working closely with industrial and academia, P S Analytical has developed a range of systems excelling at the measurement of mercury in gaseous and liquid streams. Tailoring instrumentation to customer requirements enables systems to meet required safety standards for deployment in hazardous areas on production sites.

P S Analytical has played an active part in the development of ISO/CEN standards for these measurements. In order to ensure the validity of the data recorded, PSA, in association with the National Physical Laboratory (NPL) has developed a vigorous calibration protocol that is traceable to fundamental principles. Integrating this tool into our process range of equipment ensures that reliable and authenticated data is being provided on a continuous basis.
