Описание:
The paper is dedicated to passive fillers, which are the necessary substances for a method of water activity determination in liquid samples by mirror dew-point temperature measurement. A number of such fillers for water activity analyzer Roremeter RM-10 are tested. The comparative analyses of their features and standard cellit-powder’s characteristics is provided. The following fillers are recommended as the most effective replacers of cellit: carefully dried absorbent carbon, cleaved lignin, kaolin, silicagel, pounded red and fire brick, and ceramic plate pieces.
