实验方案
With the exception of prolin, amino acids are hardly soluble in alcohols. Therefore, only the adherent moisture can be determined by the direct volumetric method.
Summary application report for analysis of moisture in Confectionery
Foodstuffs often provide a challenge for the water determination by Karl-Fischer. Instant Coffee is such a sample matrix and its water content has influence on quality and shelf life.
Accurately measure the moisture content in Magnesium Chloride (MgCl2) through Karl Fischer titration, using both Volumetric and Coulometric methods.
