| 摘 要： | 建立了微乳液毛细管电动色谱-激光诱导荧光法测定用NBD-Cl衍生后的肾上腺素和多巴胺的方法.微乳液母液的组成为w(SDS):w(1-丁醇):2(n-庚烷):w(水)=3.31:6.61:0.80:89.28.优化后的分离条件为:20 mmol/L硼酸钠+体积分数为20%的微乳液+体积分数为4%的乙腈(调pH至9.3)组成缓冲液,分离电压20 kV,峰面积和分析物浓度之间有良好的线性关系.应用本方法测定2种中药和风湿性心脏病患者血浆中的肾上腺索和多巴胺,回收率为95.8%～105.6%. |
| 关 键 词： | 微乳液电动毛细管色谱 激光诱导荧光 肾上腺素 多巴胺 |

| Abstract: | A microemulsion electrokinetic chromatography method with laser induced fluorescence detection was established to analyze epinephrine and dopamine after their having been derivatizated with 4-chloro -7-nitrobenzo-2-oxa-1,3-diazol.A stock microemulsion solution composed of w(SDS):w(1-butanol): w(n-heptane):w(water)=3.31:6.61:0.80:89.28 was prepared.The optimum separation conditions were as follows:the running buffer was composed of 20 mmol/L borate+20%microemulison(V/V)+4%acetonitrile (adjust pH to 9.3) and ... |
