补充资料：硅胶柱层析
分子式：
CAS号：
性质：以硅胶为固定相的柱色谱法。在经典色谱法中，色谱管为内径均匀、下端缩口的硬质玻璃管，下端用棉花或玻璃纤维塞住，柱管内装入硅胶吸附剂。硅胶的颗粒应尽可能保持均匀，通常直径为：0.07～0.15mm。装柱时将硅胶与流动相相混合，搅拌除去气泡，徐徐倾入色谱柱中。在经典柱色谱中，亦可采用干法装柱。在HPLC中一般采用粒度为5～10fzm的球形或无定形硅胶，柱管长为15～25cm，内径多用0.46cm，采用匀浆法装柱。当采用3恤硅胶时，柱效大于80 000片/m；当采用10μm硅胶时，柱效可大于25 000片/m。它可以进行吸附色谱法的分离，当硅胶含水大于17%时则进行分配色谱法的分离。
