说明

离子对试剂用作流动相添加剂时,可促进反相HPLC柱上离子和高极性物质的分析。流动相添加剂的纯度对其有效应用具有最高意义。Sigma-Aldrich为阴离子(季铵盐和鏻盐)和阳离子(烷烃磺酸盐)分离提供各种定制试剂。所有流动相添加剂均经过彻底测试,并特别考虑了现代反相HPLC的要求

一般描述

Ion-pairing reagents, when used as mobile phase additives, promote the analysis of ionic and highly polar substances on reversed phase HPLC columns. The purity of mobile phase additives is of highest significance for their effective application. Sigma-Aldrich makes available a variety of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) separations. All mobile phase additives are tested thoroughly with special consideration on the demands of modern reversed phase HPLC:
