等速电泳法(Isotachophoresis,简称IP)是在普通自由电泳的基础上于七十年代初发展起来的一种新的电泳技术,因为在电泳过程中各离子达到平衡后以等速泳动故称等速电泳,该法是继气相和高效液相色谱之后又一种重要的分离、分析和少量制备的手段,三者的比较见表1。 Isotachophoresis (abbreviated as IP) is a new electrophoresis technique developed on the basis of common free electrophoresis in the early 1970s, because in the process of electrophoresis, each ion reaches the equilibrium and moves at constant velocity. Isotachophoresis, this method is another important separation, analysis and a small amount of preparation after the gas phase and high-performance liquid chromatography, the comparison of the three are shown in Table 1.
