低复杂度样品纯化

左右滑动色块查看系统适合的应用范围↓

对于低复杂度样品，可以轻松或妥善地分离感兴趣的峰与杂质。
使用中至大粒径 (15 - 60 μm) 颗粒是标准应用最经济的解决方案

高复杂度样品纯化

左右滑动色块查看系统适合的应用范围↓

高复杂度样品难以分离并显示出部分重叠的峰
需要使用小粒径 (5 - 15 μm) 硅胶颗粒以提供出色的分离度 (=纯度)，但会产生高背压

从低到高样品浓度的进样

左右滑动色块查看系统适合的应用范围↓

可支持上样量最大 300g
可支持 Flash 预填充色谱柱尺寸：最大 5000g
可支持耐高压玻璃柱尺寸：直径 46-100mm
支持固体上样和液体上样两种方式

低样品浓度进样

左右滑动色块查看系统适合的应用范围↓

可支持上样量最大 1g
可支持高压色谱柱直径尺寸：4.6-70mm
支持液体进样

检测生色团化合物

左右滑动色块查看系统适合的应用范围↓

生色团化合物吸收紫外波段或可见光波段 (200 - 800 nm) 的光线
适用于紫外线检测的化合物通常含有不饱和键、芳族基或含杂原子的官能团。

检测非生色团化合物

左右滑动色块查看系统适合的应用范围↓

非生色团化合物不吸收光，因此不能通过紫外线检测器显现
典型化合物为碳水化合物
非生色团化合物可通过蒸发光散射 (ELS) 检测装置来检测
