Nickel is commonly used by the electroplating industry in processes using stainless steel, cobalt, or nickel alloys. By using nickel in certain alloys, manufacturers can achieve a product that is highly resistant to chemical stress and exhibits a longer lifespan. Nickel is also used in batteries, fuel cells, and the hydrogenation of vegetable oils in the food industry.

The HI97726 uses an adaptation of the photometric method to measure nickel concentrations up to 7.00 g/L. When the reagent is added to samples containing nickel, the sample will turn a blue hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For high range nickel determination, a narrow band interference filter at 575 nm allows only yellow light to be detected by the silicon photodetector and omits all other visible light emitted from the LED lamp. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
