DETERMINATION OF MOISTURE AND FATTY SUBSTANCES CONTENTS OF SOLID ADJUNCTS

Two new methods - moisture at 130-133 degrees C and fatty substances e xtracted by petroleum ether - were collaboratively tested by 14 labora tories (EBC and IOB Analysis Committee members and other laboratories) . For moisture the following values were obtained in the range 12 to 1 5% m/m, repeatability = 0.13% m/m and reproducibility = 0.60% m/m. For fatty substances in the range 0.3 to 0.9% m/m the following values we re obtained: repeatability = (0.06 m + 0.02)% m/m and reproducibility = (0.14 m + 0.09)% m/m. Both methods mere accepted and will replace me thods 6.1 and 6.4 respectively in Analytica EBC. The method for Fatty Substances will replace IOB methods 4.1.3 and 4.2.3. These modificatio ns will become operative on Ist September, 1996.
