The moisture content of a substance is a crucial parameter in various scientific and industrial applications. Determining moisture content accurately is of utmost importance, and several official methods are employed for this purpose. These methods adhere to standardized guidelines and provide reliable results.
This method involves drying a sample in an oven at a specified temperature until it reaches a constant mass. The moisture content is calculated as the percentage of mass lost during drying.
This technique utilizes a chemical reagent to react with water present in the sample. The amount of reagent consumed corresponds to the moisture content, which is determined through titration.
Microwave energy is utilized to rapidly heat and evaporate moisture from a sample. The moisture content is calculated based on the mass difference before and after drying.
This method involves heating a sample to a high temperature in a crucible. The volatile components, including moisture, are driven off, and the moisture content is determined by the mass lost during ignition.
