凝膠過濾預(yù)裝柱

簡要描述：凝膠過濾預(yù)裝柱LH20的分離原理是根據(jù)分子大小，主要有兩方面：以凝膠過濾作用為主，兼具反相分配的作用（在反相溶劑中）。因?yàn)槟z過濾作用，所以大分子的化合物保留弱，先被洗脫下來，小分子的化合物保留強(qiáng)，最后出柱。

凝膠過濾預(yù)裝柱產(chǎn)品介紹：

G25/G15/G10經(jīng)典的葡聚糖和環(huán)氧氯丙烷交聯(lián)介質(zhì)，具有*的選擇性，粗顆粒流速較快，細(xì)顆粒流速較慢，分辨率較高。主要用于工業(yè)上脫鹽和置換緩沖液。

LH20的分離原理是根據(jù)分子大小，主要有兩方面：以凝膠過濾作用為主，兼具反相分配的作用（在反相溶劑中）。因?yàn)槟z過濾作用，所以大分子的化合物保留弱，先被洗脫下來，小分子的化合物保留強(qiáng)，最后出柱。
如果使用反相溶劑洗脫， LH-20對化合物還起反相分配的作用，所以極性大的化合物保留弱，先被洗脫下來，極性小的化合物保留強(qiáng)，后出柱。如果使用正相溶劑洗脫，這主要靠凝膠過濾作用來分離。

我們可以提供各種凝膠過濾預(yù)裝柱，詳細(xì)信息。
