Procedure for measuring amounts of chemicals contained in hot furnace gases consists of cooling gas samples and using coherent light signal from diode laser

Taking a sample of the gas to be analyzed, cooling it to a temperature preferably below 200 [deg] C, and then measuring the quantity of chemicals, especially CO and CO 2, contained in it with the aid of a coherent light signal emitted by a tunable diode laser (TDL) through the gas and captured as it...
