Abstract
Process and apparatus for the determination of the total organic substance content of gases by a flame ionization detector, respectively comprising the steps and means for allowing components of the gas to be analyzed to diffuse through a pore-free polymeric membrane having a permeability coefficient that exceeds 10.sup.-7 Ncm.sup.3.cm/sec.cm.sup.2.Hgcm. related to the total organic substance contained in the gas, leading the gas components into a flame of another gas that contains hydrogen, passing the burning hydrogen-containing gas along one side of the membrane at a flow rate of max. 25 cm.sup.3 /min., simultaneously pumping the gas to be analyzed on the other side of the membrane at a volumetric flow of at least tenfold of that of the other gas, diffusing the organic substances to be determined through the membrane, subsequently leading the organic substances that have diffused through the membrane, in admixture with the other gas, into the flame ionization detector, and determining the total organic substances therein.
