Abstract

In a process for the determination of the inorganic carbon content of aqueous liquids, the sample to be examined, together with a carbon dioxide-free carrier gas, is introduced into a heated reaction chamber, where it is reacted with crystalline potassium bisulphate and/or a mixture of equal parts of potassium bisulphate and potassium sulphate to form carbon dioxide and water. The CO.sub.2 generated is analyzed quantitatively in a CO.sub.2 analyzer.
