1 System Components and Accessories for Sample Gas Conditioning Data Sheet 0/3-5.0 EN June 004 Vol.% A gas analysis system usually consists of two groups of devices: The gas analyzer measures the concentrations of the sample gas components and converts them into an electrical signal. Supplementary devices sample the sample gas from the process, condition it and feed it in the gas analysis system. In most cases, the sample gas sampled from the process cannot be processed by the gas analyzer without further conditioning. Too high a dust content, temperature and dew point as well as too high or too low pressure, and not least interference components in the sample gas can impair the operational capability of the gas analyzer and falsify the measuring result. Supplementary devices such as the sampling probe, the sample gas line, the sample gas cooler and pumps and filters ensure that the sample gas inlet conditions of the connected gas analyzers are satisfied and faultless measuring results are obtained independently of the process sequence and the local conditions.
