摘要: 以IEC/RP模式构建了二维液相色谱系统,采用平行交替柱捕集分析的2位十通切换阀作接口,第一维洗脱产物按10:1的分流比分流后,得到IEC和RP切换谱图.以5个标准蛋白混合物的分离评价该系统,在单独一维模式中不能分离的样品在全二维液相色谱中得到了很好的分离.

关键词: 全二维液相色谱, 蛋白质, 峰容量

Abstract: A two-dimensional liquid chromatography is established with ion-exchange chromatography(IEC) followed by reversed phase liquid chromatography(RP). The interface is a ten-port two-position switching valve coupled with two parallel RP columns. After splitting the IEC effluent with a ratio of 10:1(volume ratio), the IEC profile and the RP profile were obtained simultaneously. The system is evaluated with 5 standard proteins, which cannot be resolved in either of IEC or RP mode alone but can be resolved by the comprehensive two-dimensional liquid chromatography. The total peak capacity of this system is calculated to be 189.

Key words: Comprehensive two-dimensional liquid chromatography, Protein, Peak capacity
