DL2026 Total Nickel Automatic Online Analyzer

product overview

The DL2026 total nickel automatic online analyzer is a product of the national major water special project, which uses advanced sequential injection technology and spectrophotometry technology to detect the concentration of nickel in water. This instrument can achieve real-time, rapid, and accurate analysis of the nickel content in the sample.

working principle

The instrument adopts automatic control of water sample collection, reaction measurement, data processing, and data transmission to quickly and continuously complete the entire process of total chromium analysis in wastewater. Under high temperature and high pressure, various chromium compounds and undissolved chromium elements in the water sample are oxidized and digested by excessive nitric acid to form divalent nickel ions. In the presence of iodine/potassium iodide, divalent nickel ions are oxidized to trivalent nickel ions. Under alkaline conditions, trivalent nickel ions react with the color developer to form a complex, which changes the color of the solution. The photoelectric colorimetric device measures and records the change in the intensity of the transmitted light after the reaction complex absorbs specific wavelength light in the colorimetric cell, and obtains the response value with corresponding peak height. After comparison and calculation, trivalent nickel ions in the water sample are obtained. The ion content is used to obtain the total nickel content. The sequential injection system is controlled by a programmable logic controller (PLC) to achieve automatic analysis and obtain more accurate detection results.
