Abstract
Abstract A gas analyzer detector comprising a sorption chamber widening in the direction of the flow of a gas mixture fed to the inlet thereof. A heating coil filled with a sorbent, is arranged close to the wall of the sorption chamber, covering almost all of its length. Upon leaving the sorption chamber, the gas mixture flows around a thermal element whereon combustible components of the gas mixture being analyzed are burnt.
