22 Environmental Analysis - Focus on Mercury
New Member to the Team Ohio Lumex (USA) is very pleased to announce the hiring of Shawn Wood as Director of Compliance Technology Sales. Shawn will be focused on helping customers at a variety of sources such as utilities, cement kilns, industrial boilers, and many more to monitor for mercury with sorbent traps. By understanding a customer's flue gas conditions, he will help to determine the perfect sorbent trap formulation for each client. Through his vast experience in sampling technology, he will also be able to troubleshoot customers on their systems as well as train clients on how best to sample at various sources. Shawn will be representing our Sorbent Traps, M324 Sorbent Trap Analysers, and the IRM Mercury Process Monitor which is the perfect application for Mercury Control Technology evaluations.
Shawn comes to Ohio Lumex from Apex Instruments in Fuquay-Varina, NC where he was the Director of Engineering and General Manager. He brings many years of experience with all facets of Sorbent Trap Technology. For the last few years Shawn has been rallying around the country performing presentations, baseline testings, and trainings to help clients understand what they must do in order to monitor for mercury successfully and use sorbent traps for compliance reporting. He has been educating the industry on sorbent trap technology for a very long time and has a solid foundation to help customers make sure their equipment is working properly, that their personnel is well trained, and that they fully understand the methodology as well as the QAQC requirements of the Methods.

High Performance Mercury Analysis
As laboratories strive to efficiently deliver quality analytical results, they rely on CETAC (USA) QuickTrace™ mercury analysers. CETAC mercury analysers deliver the productivity and performance that researchers, lab managers, chemists and technicians need to meet the ever tightening worldwide regulatory demands.
Effective management of sample analysis of any kind involves getting the right instrument in place at the right time and in the right configuration. CETAC Technologies now offers four choices of analyser and four sampling configurations. CETAC offers the ultra-trace M-8000 CVAF system with or without gold amalgamation and two trace analysis CVAA systems, the M-7500 and the M-6100. Your choice of autosampler configuration includes manual sampling, ASX-130, ASX-
260 and the ASX-520 autosampler. Autosamplers range from a one rack to a four rack system with up to ninety samples per rack, fitting the needs of all laboratories.

Highly Accurate and Versatile Mercury Analysis Made Simple
The VM-3000 Mercury Vapour Monitor, from Mercury Instruments (Germany), performs continuous measurement of mercury concentration in gases. It is used in the laboratory or can be installed in locations where mercury has to be monitored. Industry people use the VM-3000 in industrial applications as well as university researchers or safety officers and personnel. It is the perfect tool for many different applications: work place monitoring, exhaust air monitoring, emissions monitoring in the chemical industry, ground air screening of contaminated areas, quality control of hydrogen and other gases and as a detector for laboratory applications.
The sample gas is fed into an optical cell by a maintenance-free membrane pump. A beam of UV light passes through the optical cell, a part of it is absorbed by the mercury atoms present in the sample. This method is called "atomic absorption spectroscopy" (AAS). It is extremely selective and sensitive. For mercury determination the AAS method is still ideal despite other, more contemporary methods being made available to the mercury analysis market. The VM-3000 is low in interference and does not require an amalgamation step or expensive carrier gases.
The VM-3000 uses a high-frequency driven electrode-less low pressure mercury lamp as its UV source. This lamp emits lines of an extremely narrow bandwidth which are congruent with the absorption lines of the Hg atoms. Cross-sensitivities are thus minimised. The extremely high stability of the UV source in the VM 3000 is a result of the reference beam feedback control method. Total background noise is less than 0.1 µg/m³
Hgtot Hg0
As with all of Mercury Instruments’ range of analysers - the use of advanced technology ensures that the VM-3000 meets the highest quality standards. Their range of instruments which includes stack emission monitors, ambient air monitors and laboratory mercury analysers comply with applicable national, European and American standards and/or regulations. These analysers are supported by a world class and worldwide network of sales and service agencies.
