Abstract
The present invention provide a water content measurement method for a hydrogen fluoride-containing compound represented by the general formula: XF.nHF (where X is either one of K, NH, Na and Li; and n is a rational number greater than 0), including the steps of causing thermal decomposition of the hydrogen fluoride-containing compound, thereby generating a thermal decomposition gas, and then, determining the water content of the hydrogen fluoride-containing compound by quantification of the water content of the thermal decomposition gas. By this measurement method, it is possible to accurately quantify the content of water in the hydrogen fluoride-containing compound XF.nHF.
