摘    要:设计了一种零死体积的柱尾连接方式和一种能使匀浆填料均匀进入色谱柱管内的锥形储料池。详述了以反相 ODS为固定相,制备高效稳定的不锈钢宽口径(0.8 mmI.D.)填充毛细管液相色谱柱的方法。系统地考察了填装方向、加压溶剂、匀浆溶剂、匀浆浓度和填装压力等不同因素对柱效的影响。在40MPa压强和优化条件下,可重复制得柱效达理论塔板数为7.5×104/m。对所测试的样品,色谱峰不对称因子为1.03~1.10。

关 键 词:填充毛细管液相色谱柱  柱制备  柱尾结构  色谱柱填充池

Abstract:The zero-dead volume union ends and conical slurry reservoir for microbore columns were designed. A detailed procedure for the preparation of highly efficient and stable stainless-steel microbore columns with reversed- phase ODS is described. The induence of packing direction, packing solvent, slurry solvent, slurry concentration and packing pressure has been studied systematically. Columns with efficiency of 75,000/m (numbar of theoretical plate) were prepared reproducibly at 40MPa packing pressure and optimized conditions. The peak asymmetric factor was 1 .03 - 1. 10 for all the compoundss tested.
Keywords:Packed capillary liquid chromatographic column  column preparation  column end structure  packing reservoir
