Dry the sample to constant weight or for the specified time and at the temperature indicated in the monograph. Dry by one of the following procedures. After drying is completed, open the drying chamber, close the bottle promptly and allow it to cool to room temperature (where applicable) in a desiccator before weighing.
INSTRUMENTATION: Drying Oven 1. 0 Scope and Application 1. 1 This method is Repeat the drying cycle until a constant weight is obtained (weight loss is less Dry the sample to constant weight or for the specified time and at the temperature indicated in the monograph.

dry weight basis. Interferences There are three general types of interferences that are of concern to this method. The first is the presence of nonaqueous (organic) compounds that volatilize during the drying stage.
Weight loss due to the presence of these organic compounds will lead to a positive bias in estimating percent moisture.

In the predrying The weight loss of reduction of 9. 5 percentage points with an 11. 24 loss of the original weight. The water shrink factor is calculated by dividing the percentage weight loss by the percentage moisture reduction. In this case, 11. 24 divided by 9. 5 gives a water shrink factor of 1. 18 weight loss for each point of moisture removed.
Loss on Drying Rodjarek Wicheintong Reference Standard Center. Bureau of Drug and Narcotic. 2 March 2012. Loss on drying (LOD) Dry to constant weight (BP 2012): Determination of Moisture Content and then by measuring weight loss; constant.
Limits of the method: Loss on drying (LOD) method. LOD is a gravimetric method that determines the weight loss of a sample after driving off volatile residuals. In this method, the temperature used needs to be warm enough and the time long enough to release all volatile components. Loss on Drying is a widely used test method to determine the moisture content of a sample. We manufacture different furnaces for this application.
