分离原理 |
葡聚糖凝胶是由直链的葡聚糖分子和交联剂 3 —氯 1 , 2 —环氧丙烷交联而成的具有多孔网状结构的高分子化合物。 凝胶颗粒中网孔的大小可通过调节葡聚糖和交联剂的比例来控制,交联度越大,网孔结构越紧密;交联度越小, 网孔结构就越疏松,网孔的大小决定了被分离物质能够自由出入凝胶内部的分子量范围。可分离的分子量范围从几百到几十万不等。 |

Glucan gel consists of linear glucan molecules and crosslinking agent 3-1, 2 - propylene oxide chloride of crosslinked with porous network structure of polymer compounds. Gel particles in the China open hole size can be adjusted by glucan and to control the proportion of crosslinking agent, the crosslinking degree, the greater the mesh structure more closely; The smaller the degree of crosslinking, mesh structure is loose, the mesh size determines the molecular weight of the separated material internal access to gel. Separable ranging from hundreds to hundreds of thousands of molecular weight. |
