Hygroscopic substances: sample preparation Sigmatik.
Absorption of water by hygroscopic substances causes the appearance of mistakes during weighting, which are impossible to statistical evaluation.Because of variability of water contained in air, we are not able it DETERMINE precisely, how much water will be absorbed by substance and how it will effect on actual quantity of substance.

Hygroscopic Gravimetric Quantitative Chemical Analysis 52868.
Hygroscopic gravimetric method is based on the determination of the absorbed water vapor mass by a dry sample after holding at a specific relative humidity and temperature. Theoretical bases of the methods are considered. Mass value of the sorbed water water content is proportional to the concentration of a heterogeneous hygroscopic impurity.
