Abstract
The invention relates to a method for determining the gas quality of a sample gas having the main components H.sub.2, CO, CO.sub.2, N.sub.2, CH.sub.4, proceeding from a spectrum of the sample gas determined by means of infrared-spectroscopy measurement methods, from which the mole fractions of the sample gas are determined by means of correlative methods, and converted into characteristic variables of the gas quality. In this connection, the optical absorption of carbon monoxide CO, carbon dioxide CO.sub.2, methane CH.sub.4 and the heat conductivity .lamda. of the sample gas are measured, the mole fraction xCO is determined from the absorption of the CO, the mole fraction xCO.sub.2 is determined from the absorption of the CO.sub.2, and the mole fraction xCH.sub.4 is determined from the absorption of the CH.sub.4, the optically not detected mole fractions of nitrogen xN.sub.2 and of hydrogen xH.sub.2 are determined from the mole fractions xCO, xCO.sub.2 xCH.sub.4 and the heat conductivity .lamda., by means of a correlation equation .lamda.=F(xH.sub.2,xCO,xCO.sub.2,xN.sub.2,xCH.sub.4), whereupon characteristic parameters of the sample gas are calculated from the mole fractions obtained in this manner.
