Awm. Lee et al., SIMULTANEOUS DETERMINATION OF DITHIOCARBAMATES BY CAPILLARY ELECTROPHORESIS WITH DIODE-ARRAY DETECTION AND USING FACTOR-ANALYSIS, Analytica chimica acta, 339(1-2), 1997, pp. 123-129
Five dithiocarbamates (DTC) (butyl-, diethyl-, dimethyl-, octyl- and p
yrrolidine-l-dithiocarbamates) are simultaneously determined by capill
ary electrophoresis (CE) with diode array detection. Three DTCs were c
ompletely separated by CE, but two (butyl- and diethyl-DTC) gave overl
apping peaks which could be resolved by heuristic evolving latent proj
ections. All compounds gave linear calibration graphs up to 50 mu g ml
(-1), with 3 sigma detection limits in the 0.1-1 mu g ml(-1) range.
