In the chemical industry, petrochemical, biochemical and other industrial fields, production and system safety is dependent upon determining reliable operation and process parameters. In a large number of these applications, gas analysis is the key to safe and efficient control of process flow, environmental protection and quality assurance in many industries, for example in power stations, air separation, sterile production and packaging in the food industry.

Many of the analysis processes used in these fields require extracting the sample gas. This inevitably is acompanied by process-related contamination such as particles or moisture. These in turn can Impact upon the measurement results or damage the measuring cells in the high quality analysers. The sample gas must therefore be conditioned before entering the analyser. Depending on the application this conditioning can consist of various levels, beginning at the gas sampling point and ending with releasing or returning the gas once analysed. Due to the often toxic and/or corrosive nature of the sample gas, conventional standard components used in general measuring and control technology cannot be used. Reliable analysis systems require units and components developed specifically for this scope of application. For over 50 years Bühler Technologies has pioneered this industry and is accepted worldwide for this type of sophisticated equipment.
