一般描述

The utilization of ion-pairing reagents as mobile phase additives allows the elution of ionic and highly polar substances using reversed phase HPLC columns. The purity of mobile phase additives is a prime factor to their successful application. Sigma-Aldrich offers an outstanding collection of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) analyzes. All mobile phase additives are rigorously tested with special emphasis on the requirements of modern reversed phase HPLC:
