Abstract
An off-gas analyzer for analyzing H2O vapor, CO, O2, CO2 and/or H2 in a furnace gas stream is fluidically coupled to a gas extraction probe. The analyzer includes an optical measurement cell having multiple sampling chambers, optically coupled to a laser. The analyzer measuring cell is housed within a heated cabinet having a heater operable to heat the interior thereof so as to maintain the extracted gas sample therein at a temperature about the condensation point of water. The analyzer allows for the analysis of the gas water vapour of wet off-gas samples.
