The determination of a specific anionic species (sodium dimethyldithio
carbamate) in waste water was performed by capillary electrophoresis w
ith direct UV detection. The application of new technology sulfonic ac
id polymer-coated capillary columns achieved sensitive analysis with r
obust electroosmotic flow (EOF), where other coated columns and conven
tional fused-silica had failed due to analyte adsorption problems. Opt
imum conditions for the separation of cationic, neutral, and other ani
onic species, including quantitative analyses of the analyte of intere
st, were obtained. The relative standard deviations for the analysis o
f anions were found to be 2.7 and 12.8% for 528 and 37 mu g/ml concent
rations, respectively. The detection limit for sodium dimethyldithioca
rbamate in waste water was established at 1 mu g/ml for typical sample
size (2 ml) without preconcentration of the analyte. The usefulness o
f capillary electrophoresis as a routine industrial monitoring tool wa
s successfully demonstrated. (C) 1997 Elsevier Science B.V.
