Product Description:
o-Cresolphthalein Complexone is complexometric reagent derived from o-Cresolphthalein. It shows violet-red color in alkaline media and is a principle compound for the determination of hardness of water.Also used as Calcium Assay Kit as direct colorimetric assay based on the O-Cresolphtalein (OCPC) method without deproteinization of the sample. The calcium determination is based on the reaction of calcium with O-Cresolphthalein complexone in alkaline solution, which yields a violet colored complex. The intensity of the color formed is proportional to the calcium concentration in the sample. Absorbance of the Ca2+-O-Cresolphtalein complex is measured at 570nm. Wavelength range of sensitivity: 560 ~ 590nm.
