The German manufacturer of gas analysers SK Elektronik (SKE) has appointed Quantitech as its exclusive UK distributor. SKE is a leading global provider of gas analysers based on the principle of Flame Ionisation Detection (FID) which is the most common technique for the measurement of Total Organic Carbon (TOC) in emissions containing solvents, petrochemicals and unburnt fuel. Key applications for the company’s analysers include environmental emissions monitoring, process gas analysis, the measurement of abatement efficiency (e.g. carbon adsorption and thermal oxidation processes), and rapid wastewater treatment plant performance measurements with VOC strippers.
Quantitech MD Ken Roberts says: “We are delighted to be working with SKE for a number of important reasons. Firstly, as a German manufacturer and developer of advanced instrumentation, SKE enjoys an excellent reputation for quality and reliability. Secondly the core FID technology is available in a number of formats to suit a wide variety of applications, and thirdly these instruments have performance certification – MCERTS for all versions and ATEX for certain models.”
One of the major strengths of the SKE instruments is their ability to measure TOC across an extraordinarily wide range of concentrations – from ppm to Vol%. The range includes both portable and fixed continuous extractive gas analysers, in addition to an IP rated in-situ model which is mounted directly on a stack or duct. All models feature automatic start-up/ignition, built-in zero gas and burner air management, automatic calibration, automatic adjustment of sample flow and require very low levels of maintenance. In addition to a choice of models, customers are also able to select from a number of options including Methane/Non-Methane Hydrocarbon measurement, internal data logging, heated sample line length, etc..
The portable Thermo-FID PT weighs just 14Kg including a gas bottle holder, or 10kg as the free-standing version. Consequently, this portable FID is ideal for stack test houses and for users with multiple monitoring locations. Explaining the importance of a portable FID with MCERTS approval Ken says: “For many years Quantitech supplied the UK market with large numbers of the Bernath 3006 MCERTS approved portable FID, but this instrument has been discontinued so those customers needing to replace their old FID now have an ideal MCERTS approved alternative, fully supported by Quantitech’s highly trained service team.”
Among the fixed FID instrument range, there is a Field Housing (FE) option for mounting in a convenient location on a wall close to the sampling point, or directly coupled to the process (MK), which reduces heated line costs and the cost of integration into a cabinet. The pre-certified, hazardous area variants of the Thermo-FID FE and MK are ideal for process operators considering solutions for compliance with ATEX Zone requirements. ATEX versions of both the Thermo-FID FE extractive VOC analyser and the Thermo-FID MK insitu analyser are available for either Zone 1 or Zone 2 classified areas.
Explaining the importance of the agreement with SKE, Ken Roberts says: “Quantitech’s MCERTS approved FTIR analysers are able to measure TOC by integrating measurements for known organic compounds. However, FID is the standard method for the measurement of TOC in the emissions of regulated processes, so in addition to stand-alone FID analysers, we will also offer the SKE FID technology as part of our integrated continuous emissions monitoring systems (CEMS).”
