In this study, the successful coupling of a 3D printed electrochemical flow cell and online multi-element analysis by ICP-OES is presented. The feasibility of the coupled method is investigated on the basis of hot-dip coated steel sheet dissolution in diluted HCl (20%). At first a qualitative evaluation of the electrochemical and element information of the coated steel substrate and relating the results to a glow-discharge optical emission spectroscopy (GDOES) measurement is done. After the qualitative evaluation, the quantitative limits are assessed by validating the linearity, repeatability and reproducibility. Comparing the results to the standard method of bulk analysis shows that the method generates reliable results. In addition the method offers the opportunity of fully automated analysis not just limited to the sample preparation.
