在同系物方法测定胶束迁移速度（ｌ／ｔｍ ｃ ） 的基础上提出了一种同时求算电渗流速率（ｌ／ｔ０） 的ｔ０ 和ｔｍ ｃ 的新方法， 该法在选择同系物标记物较为适当时， 可以得到更为准确的结果。同时可以减少由ｔ０ 测定而带来的误差。 实验结果表明， 采用甲醇等标记物测定电渗流速率时， 由于其在胶束中的溶解使得实测结果较真值偏大，而由此计算得到的ｔｍ ｃ 值偏低。ｔ０ 、ｔｍ ｃ 皆与缓冲液的种类和浓度有关， 这可能是由于缓冲液组成的变化不仅使得离子强度改变， 也使柱管壁和胶束表面的ξ势发生变化所致。同系物标记物的选择对ｔ０ 、ｔｍｃ 测定精度影响的讨论也为实际分析系统ｔ０ 、ｔｍｃ 的测定和分析分离条件的优化选择提供了必要的理论依据。
Based on the determination of the micellar migration velocity (l / tm c) by the homologue method, a new method for simultaneously calculating the t0 and tm c of the electroosmotic flow rate (l / t0) was proposed. More appropriate, you can get more accurate results. At the same time can reduce the error caused by the t0 determination. The experimental results show that when the electroosmotic flow rate is determined by methanol and other markers, the measured value is larger than the true value due to its dissolution in micelles, and the calculated tmc value is low. Both t0 and tmc are related to the type and concentration of the buffer. This may be due to the change of the buffer composition not only changing the ionic strength but also changing the ξ potential of the column wall and the micelle surface. The discussion of the influence of homologous marker selection on the determination accuracy of t0 and tmc also provides the necessary theoretical basis for the determination and optimization of t0 and tmc in the actual analysis system.
