Measurement of TOC in Electroplating Solution by TOC-L CSH

July 3, 2013

As the salt concentration in plating solutions is typically more than just a few percent, this could adversely affect direct measurement using a typical combustion catalytic oxidation type TOC analyzer. Therefore, the sample must be diluted before measurement, and because the Shimadzu TOC combustion catalytic oxidation type analyzer is equipped with an automatic dilution feature, high-salt-concentration samples can be measured by automatically diluting the sample. Here, we introduce an example of measurement of a nickel plating solution containing nickel sulfamate using the Shimadzu TOC-L CSH analyzer.
