Moisture measurement

Abstract

Reviews a wide variety of analytical methods and commercial devices for measuring moisture content in gases, liquids, and solids.

Gas chromatographic determination of water in natural products by reaction with 2,2-dimethoxypropane

“…The natural products used in this work were obtained from a commercial source. 1 Gravimetric Method for Water DeterminatiowThe water content of all the products, except caraway, cinnamon, clove, ginger, and peppermint, was determined by the N F XI1 procedure (25) for vegetable drugs containing no constituents volatile at 105". The water content of caraway, cinnamon, clove, ginger, and peppermint was determined by the N F XI1 procedure (25) for vegetable drugs containing ether-soluble constituents volatile at 105".…”

“…A wide variety of analytical methods are used in many fields for the determination of water. Ewing (1) has found more than 25 distinct methods for this purpose. Among the procedures which have been the subject of recent investigation, GLC has proved to be particularly well-suited for the analysis of water in different organic systems.…”
