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.
