英文摘要	capillary electrophoresis with capacitively coupled contactless conductivity detection ( c4d) was used for the simultaneous determination of inorganic anions and cations by dual opposite ends introduction. the effects of the alternating current voltage and frequency on the detection sensitivity of c4d, the conceptration and ph of 2-(n-morpholino) ethanesulfonic acid (mes)/histidine (his) running buffer, and the injection mode of sample on the separation of cations and anions were studied. twelve inorganic cations and anions were determined in less than 4 minutes by the injection mode of cations being first introduced, followed by anions from the oppositecapillary end under the best conditions, which were vltage 200 v, frequency of 200 khz, 20 mmol/l mes/ 15 nunol/l at ph 5. 0. the detection limits of cations were 0.2 ( na+) to 3 ( mn2+) mu mol/l, anions 0.5 (so42-) to 4 ( br-) mu mol/l. the responses were linear ( correlation coefficients r = 0. 9957 similar to 0. 9999) over two orders of magnitude. the method could be used for simultaneous determination of both cations and anions in real water samples.
