Nickel

Description

The determination ranges of the nickel analyzer vary from trace μg/L to 200 mg/L using the (optional) internal dilution module.

Method

In the presence of an oxidizing agent, nickel ions react with dimethylglyoxime in an alkaline solution to form an orange-brown colored complex. The absorbance intensity is proportional to the nickel concentration in the sample and is determined at 470 nm.
