Focus on Merury - Environmental Analysis - UK Focus Mercury Levels in Soil – Environmental Reference Materials
LGC Standards (UK) expands its range of certified reference materials (CRMs) for environmental factors with the introduction of three new materials for mercury in soil. One of the most significant contributors to mercury in the environment is from mining activities, driving specific requirements for environmental testing. To ensure test results are reliable and of the required quality, laboratories need high quality reference materials of appropriate mercury concentrations. This has led to an increase in the demand for CRMs for mercury in soil, where availability to date has been limited. To respond to this worldwide demand, the Central Geological Laboratory of Mongolia (CGL) has now developed three new certified reference materials for mercury based on mineral and natural soil.
Manufactured under the CGL’s ISO 17025 accreditation and strictly following the requirements of ISO 30 - 35 guidelines, these three new CRMs for mercury in soil are now available from LGC Standards in 30g or 50g units.

askus@lgcstandards.com.... Reader Reply Card No. 139 Portable Mercury Analysis in Oil & Gas
The Jerome 405 is redefining the portable mercury vapour analyser market by way of significant performance enhancements and modern communication capabilities creating the optimum method for mercury spill detection and clean up analysis. It is considered the instrument of choice within the UK Oil and Gas industry, with many major oil companies and operators already taking advantage of its impressive capabilities.
With increased emphasis on health and safety, reliable, fast and accurate mercury monitoring is vital when breaking containment of pressurised vessels containing hydrocarbons. The Jerome 405 utilises industry proven, inherently stable and reliable gold film sensor technology and simple one button operation combined with significantly low detection capability. The sensor is highly specific for mercury, eliminating interferences common to ultraviolet analysers such as water vapour & hydrocarbons and has a detection range of 0.5 to 999ug/m3 with a response time of 2 seconds in survey mode.
Additional applications include mercury spill response and clean up, exclusion testing, facility monitoring, source surveys, fluorescent lamp disposal and recycling, landfill monitoring, exhaust duct monitoring, plant environmental monitoring. For further information regarding Jerome Analysers please contact ABLE Instruments (UK).

A Flexible Tool for Aqua Regia Digestion of Trace Metals
Heavy metals are ubiquitous in the environment and can easily enter the food chain, affecting the endocrine system. According to regulations (DIN, EN, ISO) soil, sludge, water and electronic waste samples have to be digested with aqua regia under reflux, followed by ICP-MS analysis.
With BUCHI’s (Switzerland) SpeedDigester, it is possible to digest up to twelve samples simultaneously under reflux with aqua regia. Loss of volatile metals is prevented using absorption tubes. For very inhomogeneous samples, the SpeedDigester excels compared to other technologies due to its large sample vessels (250 mL). The temperature controlled IR digestion together with an excellent thermal homogeneity ensures fast digestion leading to high reproducibility and reduced foam formation. Emission-free operation is guaranteed with the ultimate four-stage Scrubber. In addition, the SpeedDigester can be easily used for the determination of COD, TKN and phosphate levels.

Mercury Detection in Crude Oil at Innovene Grangemouth
Levels of mercury in crude oil vary depending on the source of the oil. The Innovene Grangemouth site sources its crude oil feedstocks from around the world which may contain differing levels of mercury. To assist in detection of mercury contamination in crude oil streams the highly sophisticated Arizona Instruments Jerome 431-XE Mercury Analyser, supplied by ABLE Instruments (UK), is used within many of the different plants, measuring the mercury vapour levels in oil pipelines and storage vessels.
An Occupational Hygiene Specialist working for Innovene confirms: ‘The main importance of mercury measurement is to protect employees health. There are certain strict limits to which we adhere. If the levels detected exceed these, we change the way in which we carry out certain operations, for instance issuing breathing apparatus. The Jerome is used because the analysis is almost instant. With other methods, the samples have to be sent to laboratories for analysis, which simply takes too long.’

Total Mercury Emission Monitor Achieves EN15267-3
Verewa’s Total Mercury Emission Monitor achieves EN15267-3 Certification. As part of DURAG GROUP(UK), Verewa has been manufacturing approved Mercury continuous emission monitors for over 15 years.
From the outset, the HM-1400 TRX total Mercury monitor was designed for emissions monitoring. Integral to that design is a technique that provides a “true” continuous measurement without the aid of pre-concentration and carrier gases. Interferences are all but eliminated using a patented Dual Beam UV Photometer and an optional switching solid Catalytic Converter can offer both “total” and “speciated” Mercury measurements. A very important focus for the design was optimising maintenance intervals and reducing running costs to a minimum.
An optional automatic calibration module can be used to introduce a Mercury sample at the heated sample inlet, thus ensuring calibration of the complete system.
As legislation becomes more stringent and the requirements of modern CEM Systems become more challenging, we are safe in the knowledge that the HM-1400 TRX Total Mercury Emission Monitor achieves EN15267-3 Certification..... Reader Reply Card No. 143 Reader Reply Card No. 200

Monitoring Mercury Levels in the Environment Utilising Laboratory and Process Instrumentation
For nearly 30 years P S Analytical (UK) has been developing Atomic Fluorescence instrumentation for both laboratory and process applications to determine mercury in its various species in gases, liquids and solids at ultra-low levels.
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 instrumentation routinely provides relevant data to define reliable removal strategies and create a safer environment. 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 has developed a specific calibration device that data obtained is fundamentally correct and fit for purpose. Tailoring instrumentation to customer requirements enables systems to meet the local and international required safety standards for deployment in hazardous areas on production sites.
