Moisture content determination is a crucial aspect of compound identification, influencing various properties and applications. Official methods establish standardized procedures to ensure accuracy and consistency in moisture determination.
This method involves drying a sample at a specific temperature and weighing it before and after drying. The weight loss represents the moisture content.
A sample is subjected to distillation, and the condensed water is collected and measured. The volume of water collected indicates the moisture content.
This method uses a chemical titration to determine the moisture content by reacting with a Karl Fischer reagent. The volume of reagent consumed corresponds to the moisture content.
A sample is heated in a microwave oven to remove moisture. The weight loss is then measured to determine the moisture content.
Selection of the appropriate method depends on factors such as sample type, accuracy requirements, and available equipment.
