Moisture AnalyzerIt is a routine inspection item in drug standards such as the Chinese Pharmacopoeia, aimed at controlling the water content in drugs to prevent mold growth, hydrolysis, oxidation, etc. Taking advantage of the low solubility of water in toluene and the low boiling point of toluene, toluene and a certain amount of sample are placed in the device. The moisture and toluene vapor of the test variety are evaporated together, and the distilled liquid is collected. After cooling, the moisture content of the test variety is read from the moisture measurement tube after the water and toluene separate.Azeotropic distillation methodThe water and toluene in the sample are distilled to form an azeotropic binary mixture, which is distilled out. The density of water and toluene is different, and they are layered in the receiver. The moisture content is calculated based on the volume of distilled water.
