一般描述

LC-SCX 阳离子交换色谱柱带有强酸性的丙磺酸基，用于分离阳离子。可通过调整 pH、离子强度和添加剂浓度来调节保留时间和选择性。

应用

在™从人尿液中纯化和表征 8-羟基鸟嘌呤 (oh 8 Gua) 期间使用了 Supelcosil LC-SCX HPLC 色谱柱。它被用作阳离子交换柱，以采用高效液相色谱-电感耦合等离子体质谱法 (HPLC-ICP-MS)测量和提取水溶性砷及冻干海洋动物组织。它还被用于砷化合物的色谱分离。它还可作为阳离子交换色谱柱，以采用高效液相色谱-电感耦合等离子体质谱法 (HPLC-ICP-MS) 分离、鉴定和测定牡蛎组织 和海褐藻样 （如Hijiki fuziforme ）中的砷化合物。
