In emission measurement, process control relies on prompt and exact determination of the operating parameters. Here, gas analysis is the key for safe and efficient control of process flows, environmental protection and quality assurance. This benefits controlling flue gas emission in power stations as well as measurements in small combustion plants or exhaust gas analysis in automotive engineering. Many of the analysis processes used in these fields require extracting the sample gas. This inevitably also extracts process-related contamination such as particles or moisture. These in turn can impact the measurement results or damage the measuring cells. The sample gas must therefore be conditioned before entering the analyser. The EGK 2-19+ series features a new generation heat exchangers with a particularly low wash out effect of watersoluble components and are specifically suitable for measuring emissions. Particularly the wash out effect of SO2 is low. These coolers can therefore be used for so-called automated measuring systems (AMS) per EN 15267-3.
