What Is Moisture Content Analysis? - Scientist Live

Apr 01, 2013 Oven drying methods for moisture determination are commonly used for commercial purposes. The oven-drying methodology consists of heating by convection with forced or circulating hot air. The accuracy and moisture range that oven-drying techniques offer is very similar to other thermogravimetric methods.
