-
On the self-constructed electrochemical detection system,antipyrinum and amidopyrine in injection antondint were separated and determined by capillary electrophoresis with amperometric detection(CE-AD).Under the optimized conditions:a running buffer composed of 30 mmol/L Na2B4O7 buffer pH 9.0,separation voltage 20 kV,injection time 8 seconds and detection voltage 0.8 V,a linear relationaships between peak areas(Y) and mass concentrations(c) of the two analytes were established,with a determination limit of 0.1 mg/L for antipyrinum and that of 0.05 mg/L for amidopyrine,respectively.
