描述

Application

酸性、碱性和中性药物 RP-HPLC 分离中的流动相改性剂。通过抑制拖尾提高氨基酸和氨基​酸酰胺的 HPLC 分离度。

Triethylamine, a mobile-phase modifier in the RP-HPLC separation of acidic, basic and neutral molecules, improves the resolution of amino acids and amino acid amides by HPLC by suppressing tailing and the stability of drugs and other compounds.
