Zinc

Description

The determination ranges of the zinc analyzer vary from trace μg/L to 125 mg/L Zn2+ using the (optional) internal dilution module.

Method

Zinc reacts with the reagent zincon in a buffered alkaline solution to form a blue complex. The absorbance intensity is proportional to the zinc concentration in the sample and is measured at 660 nm.
