摘要: 建立了一种同时分离检测包括利尿剂、蛋白同化剂、β-阻断剂、麻醉剂、β2-激动剂、刺激剂等6类8种兴奋剂的毛细管区带电泳-紫外检测法。优化的色谱条件为:以50 mmol/L甲酸铵-氨水(pH 7.8)缓冲液为运行液,于3 kPa下进样10 s,分离电压为20 kV,检测波长为214 nm。在此条件下,8种兴奋剂在7 min内实现了快速的基线分离。在相应的浓度范围内,8种组分的浓度与峰高呈良好的线性关系,检出限达为0.2~0.7 μg/mL。该方法快速,分析成本低,无污染,非常适用于多种类兴奋剂的同时快速检测。

Abstract: 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, β-blocks, narcotics, β2-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 μg/mL. It is a simple and rapid method with small sample size for doping detection.
