Qa3’s client required a portable direct AAS mercury analyser that could be deployed to remote locations to determine mercury in a clean and dry natural gas stream with minimal time on site. An investigation of the new Lumex RA-915M mercury analyser compared with larger and less portable equipment that typically employ gold amalgamation, pre-concentration and subsequent regeneration steps was carried out.
在汞浓度使用新Lumex公司的RA-915M汞分析器参照校准气体测定（汞在氮气）在与总的燃烧中氧的AAS汞仪相对约3％的一种的平均差值的良好的协议中度测量范围大6-21ug / m3
QA3s客户端应用程序是一个干处理烃类气体，无芳烃现在和结论的Lumex公司RA-915M可以调动到偏远地区和电池供电使用，如果需要，交叉检查与燃烧/ goldtrap / AAS人优秀协议校准气体只有3％的相对差异
David Walls, Analytical Chemist at Qa3 commented that ‘the latest software is much improved and not only offers the user much improved functionality but also records all results for traceability and quality purposes’ Qa3 has over ten years experience using the original Lumex RA-915 mercury analyser which continues to be in service. The new model has proven to be robust and reliable.
Mark Brereton, Managing Director of Leeds based Spectronic Camspec which supplied the instrument said he was delighted with the results under test by Qa3. It’s now already in revenue earning service and looked like being as successful and profitable as the original still in use.
