摘要

Use of zwitterionic adsorbents for the liquid chromatography, wherein the adsorbents have a solid support, which has a porous structure, and wherein the adsorbents are made according to a method comprising the steps of:a) reacting a silane compound of general formula i (Formula i) with either a sulfonic acid compound of the general formula ii # # str3 # # (Formula ii) or with a sulfonic acid compound of the general formula iii # # str4 # # (Formula iii # # str4 # #), ..
