Moisture Analysis/Water Activity
Moisture Analysis/Water Activity
Water Activity:
Analysis is performed with a chilled mirror dew point moisture analyzer. Water activity, Aw, is the partial vapor pressure of water in a substance divided by the partial vapor pressure of pure water at the same temperature.
Moisture Analysis (Weight Loss on Drying):
Analysis is performed with an analytical balance and drying oven. The method measures the weight loss on drying due to the loss of moisture and volatile compounds.
