研究了用毛细管区带电泳法快速分离检测甲基安非他明和安非他明的方法．在３５０ ｍ ｍ ｏｌ／Ｌ（ｐＨ ３．１） 的磷酸盐缓冲体系中，上述两种组分可在６ ｍ ｉｎ 内完全分离．以紫外检测器在１９５ ｎｍ 处检测安非他明和甲基安非他明，１４ 次平行测定的相对标准偏差ＲＳＤ分别为３．１％ 和２．２％ ，在５×１０－ ６－ ５００×－ ６的范围内，安非他明和甲基安非他明均有较好的线性（ｒ ＞ ０．９９９），结果表明该方法在较大的范围内有良好的线性关系和较好的重现性．
A rapid method of capillary zone electrophoresis for the detection of methamphetamine and amphetamine was studied. In 350 m mol / L (pH 3.1) phosphate buffer system, the two components can be completely separated within 6 mins. The detection of amphetamine and methamphetamine at 195 nm by UV detector showed that the relative standard deviations (RSDs) of 14 replicates were 3.1% and 2.2%, respectively. The relative standard deviations (RSDs) at 5 × 10-6- 500 × - 6, both amphetamine and methamphetamine had good linearity (r> 0.999) and the results showed that the method had a good linear relationship over a large range and a good weight Reality
