28 Mercury Analysis
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 Atomic Fluorescence 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 the local and international 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.

Mercury as a Global Pollutant
From July 28th – August 2nd 2013 the 11th ICMGP International Conference on Mercury as a Global Pollutant will take place in Edinburgh, Scotland.
www.mercury2013.com
Over 1,000 professional and academic experts on all aspects of Mercury behaviour and control will gather together to discuss a variety of Mercury monitoring and treatment topics.
The negotiations of the Global Mercury Treaty are to be completed in early 2013. The Edinburgh conference, therefore, presents a very timely opportunity for information sharing between the scientific community and policy makers based on the agreed text. Each day of the Edinburgh meeting will start with discussions that highlight some of the related challenges ahead in an effort to promote understanding and foster increased understanding of the treaty.
The five day event will continue with parallel sessions and hundreds of posters covering all
areas and aspects of mercury research. It will include research relevant to UNEP’s Mercury Programme and actions that countries may need to take to implement the mercury treaty. Topics will include waste, chlor-alkali, coal combustion, gold mining, dentistry as well as the movement, behaviour and effects of mercury in our environment. Once again, the UNEP Global Mercury Partnership will host a special session dedicated to its work. The conference will be accompanied by the largest ever exhibition of organisations including commercial companies that provide services for mercury management, monitoring and control from all sources. There will also be public outreach activities to help bridge the gap between those that know and those that need to know. Edinburgh is one of the most beautiful and historic cities in the world. Where better to look from the past into the future?

Are you unsure which mercury analysis technique is right for your application? There are many techniques available today ranging from digestion- free analysis to cold vapor atomic absorption and fluorescence as well as a growing number of standard methods and regulations that call for their use. As a result, choosing the right technique can be challenging for many. To address this, Teledyne Leeman Labs has developed a simple to use online tool to help you make the best mercury analysis choice. Visit their mercury selector tool on their website and find out which Hg analyser is the perfect fit for your laboratory.

Web-based Selector Tool for Mercury Analysers
Mercury Vapour Analyser Eliminates Instrument Downtime
The Ion Science (UK) Mercury Vapour Indicator (MVI) is a robust, reliable mercury analyser that does not saturate or need regenerating between readings, eliminating instrument downtime.
MVI is proven to achieve outstanding results out in the harshest of environments, even with extremely high levels of mercury vapour. MVI units are providing fast and accurate mercury vapour readings, ensuring the health and safety of workers.

MERCURY ANALYZERS
MVI gives a real time response within just 3 seconds. Ready to detect instantly, MVI provides continuous readings and offers two detection ranges: 0.1 to 200 and 1.0 to 1999 microgram/cubic meter.
MVI utilises a high performance pump for fast indication and recovery. The instrument’s audible alarm and large digital display clearly indicate the levels of mercury present.
Ergonomically designed with simple, one handed operation MVI is the ideal survey unit for rapid, accurate mercury vapour detection in the most challenging of environments.
Target applications for MVI include manufacturing, recycling and fluorescent lamp processing plants, mining, petroleum, bioremediation, hydrocarbon and refining.
