title: Determination of low-molecular-mass anions in coating samples by capillary electrophoresis with conductometric detection.
abstract: A method for the rapid analysis of low-molecular-mass anions in electrodeposition coatings has been developed, employing capillary electrophoresis with a nonsuppressed end-capillary conductivity detector. After optimization of the carrier electrolyte, quantitative determination of all analytes of interest (including inorganic anions and organic acids) was possible in less than 11 min. The results obtained by capillary electrophoresis did not show any significant differences with the manufacturer's data originating from the more time-consuming ion-chromatographic analysis.
