We describe a technique for measuring the water content of stools by the Karl Fischer method. The analysis is based on removal of water into a mixture of methanol/chloroform (1/2), after dispersion of the stool by sonication in presence of solvent. An aliquot of the solution thus obtained is placed in themeasuring cell of a Karl Fischer apparatus and then analyzed in the classic way. We further describe the advantages of this method (odorless, precise, reproducible) in contrast to other current methods. In addition the same organic solution can also be used in determining the lipid content of stools.
我们描述了一种用卡尔费休法测量粪便含水量的技术。该分析基于在溶剂存在下通过超声处理使粪便分散后，将水分去除到甲醇/氯仿（1/2）的混合物中。将由此获得的溶液的一份等分试样置于卡尔费休仪器的测量池中，然后以经典方式进行分析。我们进一步描述了该方法相对于其他现有方法的优点（无气味、精确、可重现）。此外，相同的有机溶液也可用于测定粪便中的脂质含量。
