A capillary zone electrophoresis-ultraviolet detection (CZE-UV) method was established for the simultaneous determination of eight doping agents which belong to diuretics, anabolic steroids, beta-blocks, narcotics, beta2-agonists and stimulants. Under the optimal conditions, with 50 mmol/L ammonium formate buffer (pH 7.8) as the running buffer, injection at a pressure of 3 kPa for 10 s, applied voltage of 20 kV, and detection at 214 nm, eight doping agents were separated quickly and completely within 7 min. The linearities of the eight doping anents were good in respective concentration ranges. Their detection limits were from 0.2 to 0.7 microg/mL. It is a simple and rapid method with small sample size for doping detection.
建立了一种毛细管区带电泳 - 紫外检测（CZE - UV）方法，用于同时测定属于利尿剂、合成代谢类固醇、β受体阻滞剂、麻醉药品、β2激动剂和兴奋剂的8种掺杂剂。在最佳条件下，以50 mmol/L甲酸铵缓冲液（pH 7.8）作为运行缓冲液，在3 kPa压力下进样10 s，施加电压20 kV，并在214 nm处检测，8种掺杂剂在7分钟内快速、完全分离。8种掺杂剂在各自浓度范围内线性良好。它们的检测限为0.2至0.7μg/mL。这是一种用于掺杂检测的简单快速方法，进样量小。
