摘要： Compositions, kits, and methods of using the kits and compositions to determine the hardness of and/or magnesium concentration in a solution are described. The kit can include a lyophilized composition that has an absorbance at a detectable wavelength in response to the hardness of the solution and or the concentration of magnesium in the solution.

摘要： A composition and an assay solution for the determination of dissolved borate concentration comprising a catechol dye, a solubilizing agent, and a buffer are described. The composition and assay solution may further comprise a solubilizing agent. The catechol dye acts as a chemical borate sensor. The chemical borate sensor changes its optical properties upon binding to borate. The multivalent cation chelator binds multivalent cations present in a sample being analyzed. The buffer prevents changes in pH. The solubilizing agent aids in solubilizing the catechol dye, multivalent cation chelator, and/or the buffer.
摘要翻译： 描述了用于测定溶解的硼酸盐浓度的组合物和测定溶液，其包含邻苯二酚染料，增溶剂和缓冲剂。 组合物和测定溶液可以进一步包含增溶剂。 儿茶酚染料用作化学硼酸盐传感器。 化学硼酸盐传感器在结合硼酸盐时改变其光学性质。 多价阳离子螯合剂结合正在分析的样品中存在的多价阳离子。 缓冲液可防止pH变化。 增溶剂有助于增溶儿茶酚染料，多价阳离子螯合剂和/或缓冲液。
