Analysis of Organic plating Bath Additives and Chemicals by Isocratic HPLC

In today’s world, over 75% of all metal surfaces on manufactured metal “items” have some sort of plated finish on them. From highchromium steel car bumpers to zinc diecast toys to Silver-contact electronic components. While the primary composition of these plating baths are inorganic (the metals and salts that are used to make up the desired metal finish), almost all types of plating baths; from alkaline cyanide to acid sulfate to neutral borate, and so on; employ some sort of organic chemical to improve the quality or characteristics of the plate. These compounds are added to the bath in a certain concentration range to control the hardness, brightness, shine / matte texture, conductivity, density, etc.; of the final product.
