产品简介

与典型C18键合相相比，为芳香化合物提供互补选择性

详细介绍

CORTECS苯基柱

CORTECS苯基柱是CORTECS色谱柱家族的新成员，为CORTECS C18柱提供互补的选择性。基于的pi-pi作用，苯基柱能够为芳香化合物提供的选择性。使用质子性溶剂如甲醇，能够进一步增强pi-pi作用。

CORTECS苯基柱的优势：

与典型C18键合相相比，为芳香化合物提供互补选择性
低pH条件下键合相稳定无流失
兼容LC-MS

CORTECS苯基色谱柱对硝基芳香化合物分离的选择性

硝基芳香化合物几乎不会在自然界中自发形成，它们主要通过人工合成，染料、聚合物、杀虫剂和中都含有该类物质。大规模地合成此类化合物会造成土壤和地表水污染，最终引发环境问题。硝基赋予了此类分子多样的化学性质和功能，但也导致这些物质难以进行生物降解。由于这类物质具有抵抗氧化降解的能力，其本身又具有急性毒性、致突变性，而且易被还原为致癌性的芳香胺，因此它们的抗降解性问题尤为棘手1 。环境保护署(EPA)已将这些物质列为有害物质，并且认为它们会危害人体健康。本应用纪要将探索如何应用CORTECS苯基色谱柱高效且有效地分离这类化合物，并研究甲醇和乙腈对分离的影响。无论是对于节省成本还是开发更出色的色谱方法而言，了解溶剂选择对分析选择性的影响都具有重要意义。本研究将使用一种计算溶剂强度的方法展示乙腈和甲醇在 CORTECS C8 色谱柱和CORTECS苯基色谱柱(2.7 µm填料)上的选择性差异2 。
