In the chemical industry, petrochemistry or biochemistry, reliable 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 or exhaust gas analysis in automotive engineering, as well as the efficient control of air separators or sterile production and packaging in the food industry. 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. Many applications require equipment which can be used in explosive areas. This is where the TC- tandard X2 series provides solutions for Zone 2 or Class I, Division 2. Despite its small size, the TC-Standard X2 sample gas cooler already covers a large percentage of standard applications in gas analysis.
