Hardness
FEATURES:

The reagents are exceedingly stable, especially the amine buffer. The method is also extremely sensitive permitting ppb ranges to be measured.

MEASURING PRINCIPLE:

 Colorimetric

The calcium and magnesium form a complex with the cresolphthalein complexone, which on adding the buffer, which brings the pH to about 9.6, a characteristic purple complex is formed. If only the calcium to be measured the magnesium may be complexed by the addition of 8-hydroxyquinoline to Reagent #1
