[Case Study] Quantitative Analysis of Brighteners and Decomposition Products in Electrolytic Nickel Plating Solutions

Management of gloss agents and decomposition products using a single quadrupole mass spectrometer LC-MS enables stable quality assessment of plating solutions!

Quantitative analysis of gloss agents (saccharin and 2-butin-1,4-diol) in electroplating nickel plating solution using LC-MS helps maintain a consistent composition of the plating solution and greatly aids in the quality control of gloss agents. This method analyzes the components contained in the gloss agents under two different conditions based on their chemical composition. Additionally, samples can be easily measured by simply diluting them with water, and good results ranging from 92% to 108% have been obtained in addition-recovery tests. Furthermore, analytical conditions have been devised to achieve stable measurements over a long period. By using MS, detection is possible even at low concentrations in samples containing high concentrations of impurities, such as plating solutions, and detection is possible with both UV and MS. Measurement of not only gloss agents but also decomposition and by-products is possible, leading to further evaluation of the plating solution.
