Compositions, apparatus, and methods for determining hardness of water and magnesium ion in an analyte composition
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.
