美国Sigma-Aldrich旗下Fluka品牌 容量法双组份滴定剂（卡尔费休试剂）
描述：
Karl Fischer volumetry is used for samples with high water content, i.e. 1-100 mg per sample. An iodine-containing solution serves as titrating agent. The water content of the sample is calculated using titration volume and titer of the titrating agent. HYDRANAL one-component reagents conveniently contain all reactants (iodine, sulfur dioxide and a base) dissolved in a suitable alcohol in one solution, whereas HYDRANAL two-component reagents contain all necessary reactants separated in two different solutions to enhance the rapidity of the Karl Fischer reaction and the titer stability of the titrating agent.
