Stack VOC Determination using a Portable, Cutting Edge Analyser

The problem - Emissions of Volatile Organic Compounds (VOCs) from industrial chimneys are becoming an issue of global importance, and to posess accurate knowledge about how to test VOC is a wise strategy. VOC emissions are quantified and monitored according to standard EN 12619, using an FID analyser which uses hydrogen and other reference gases in pressurised cylinder. Operators must then approach the sampling point, often placed several meters from the ground, climbing chimneys of industrial settlements with instruments and cylinders. Is it possible to make this job easier and safer?

Using the Polaris FID analyser, from Pollution Srl (Italy), it is possible to carry out VOC monitoring according to EN 12619 without lifting accessories and heavy weights typically involved with FID analysers.

So far, the portability of such analysers was a feature of FID designed for fugitive emissions from valves, flanges, gaskets, pumps or compressors monitoring. Moreover, when VOCs are measured in chimneys according to EN 12619, the analyser must be much more robust and fully heated to 180°C, leading to increase in size and weight.

Polaris' FID analyser complies with this standard regulation, but the real breakthrough is the unmatched portability and the next generation technology.

Polaris FID is a new concept and incorporates these important features: two rechargeable batteries that last more than three hours; a zero air cylinder for 10 hours of continuous measurement; a span gas cylinder useful for tens calibrations and, last but not least, an advanced metal hydrides cartridge for hydrogen storage to fuel the flame detector. However, the hydrogen source is not the usual pressurised cylinder, but a small steel cartridge that weighs only 500 grams, and which stores hydrogen for 30 hours of continuous measurements. Furthermore, as hydrogen is chemically bonded to a special metal alloy inside the cartridge, there is no risk of leakage and explosion: hydrogen cylinder will not be a concern anymore.

In conclusion, the Polaris FID incorporates everything needed for a measuring campaign in just 13 kg and a compact body, making it the best choice for the operators who have to climb on the chimneys of industrial settlements easily and safely.
