Microwave Oven Moisture Analyzer

Microwave oven moisture analyzers are automated analytical instruments employed in various sectors to accurately determine moisture content. This crucial information assists in product safety assessment, quality control, and research and development.

Official Methods of Moisture Content Determination

Several official methods are recognized for moisture content determination, including:

Gravimetric Methods: Drying samples to a constant weight at specified temperatures using techniques like oven drying, vacuum oven drying, or freeze drying
Microwave Oven Drying: Utilizing microwave energy to rapidly heat samples and quantify weight loss, as per AOAC 938.05 and ASTM D6342
Infrared Drying: Employing infrared radiation to remove moisture content, as specified in ISO 6496
Karl Fischer Titration: Volumetrically determining moisture content by reacting the sample with Karl Fischer reagent, in accordance with ASTM D6304 and D6869
Distillation Methods: Extracting moisture content through distillation, as per AOAC 926.08 and ASTM D3765
