Abstract
Abstract A gas conditioning and analyzing system for conditioning and analyzing a sample of gas of any given temperature, composition and moisture content. The system receives a sample of gas from a source in a conduit leading to a detection chamber and the detection chamber has a liquid reservoir for conditioning the sample and a detecting unit for gas analysis. Separate gas and liquid outlets from the detection chamber are provided with the gas outlet leading to a flame checking chamber for release of the gas under liquid after which the gas and liquid are passed out of the chamber in a conduit leading to a discharge point. The liquid outlet leads to a liquid level regulator chamber from which the liquid is discharged from the system. The system is able to analyze potentially explosive mixtures of gases in a safe, continuous and rapid manner.
