Mobile Mercury Analyser Proves Itself in Tests

When a mercury analyser provided by Leeds based Spectronic Camspec (UK) was field tested against larger and less portable equipment the results impressed Qa3’s Analytical Chemist, David Walls. The Lumex RA-915M Mercury Analyser uses AAS similar to that employed by other direct mercury analysers but with the addition of a unique Zeeman background correction function. 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. The trial involved the analysis of a calibration gas over a seven day period.

The mercury concentrations determined using the new Lumex RA-915M mercury analyser with reference to the calibration gas (Hg in nitrogen) was in excellent agreement with that of the total combustion in oxygen AAS mercury analyser with an average difference of approx 3% relative to a moderately large measurement range of 6-21ug/m3.

Mark Brereton of Spectronic Camspec said he was delighted but not surprised - ‘It’s an outstanding product’ he said.
