概述
Sepax SEC键合固定相是采用的表面修饰技术，通过在高纯度具有良好机械稳定性的硅胶基质上，键合一层均匀的纳米厚度的中性亲水涂层而制备得到。由于采用可控的化学修饰技术，因此能确保柱与柱之间有着可靠的重现性。SEC填料采用化学键合技术，表面亲水涂层覆盖完全，因此不仅具有优异的稳定性，而且对蛋白等生物样品的非特异性吸附作用也非常小。精心设计的大孔体积可保证高的分离容量以及优异的分辨率。广泛应用于生物分子及水溶性聚合物的分离和检测。
SRT体积排阻色谱柱优点 大的孔体积，高的柱容量，高的柱效，良好的重现性 宽的pH范围（pH范围2-8.5） 寿命长，一般在700-1000针 低盐浓度洗脱，适合LC-MS分析 对于生物样品常见的PEG或者吐温80等物质无强吸附 高的蛋白回收率，且蛋白不易失活 极低的非特异性吸附 不会出现二聚体与单体出峰紊乱的现象 解决多维色谱分析应用应用领域
蛋白药物 （人血白蛋白、免疫球蛋白、HGH、EPO等） 多肽(Peptide) 水溶性多聚物（多糖、PEG） 抗生素（头孢类抗生素） 抗体（Antibodies）、疫苗（Vaccine） 病毒蛋白(Virus Protein)、细胞发酵液、DNA
