CALCIUM OCC

TOTAL
Colorimetric method
ENDPOINT

 

PRINCIPLE

The method is based on the specific binding of cresolftalein complexone (OCC), a metallochromic indicator, and calcium at alkaline pH with the resulting shift in the absorbtion wavelength of the complex. The intensity of the cromophore formed is proportional to the concentration of total calcium in the sample.
