CORTECS苯基柱是CORTECS色譜柱家族的新成員，為CORTECS C18柱提供互補的選擇性。基于獨特的pi-pi作用，苯基柱能夠為芳香化合物提供獨特的選擇性。使用質子性溶劑如甲醇，能夠進一步增強pi-pi作用。
CORTECS苯基柱的優(yōu)勢：
與典型C18鍵合相相比，為芳香化合物提供互補選擇性
低pH條件下鍵合相穩(wěn)定無流失
完全兼容LC-MS
CORTECS苯基色譜柱對硝基芳香化合物分離的獨特選擇性
硝基芳香化合物幾乎不會在自然界中自發(fā)形成，它們主要通過人工合 成，染料、聚合物、殺蟲劑和炸藥中都含有該類物質。大規(guī)模地合成 此類化合物會造成土壤和地表水污染，最終引發(fā)環(huán)境問題。硝基賦予 了此類分子多樣的化學性質和功能，但也導致這些物質難以進行生物 降解。由于這類物質具有抵抗氧化降解的能力，其本身又具有急性毒 性、致突變性，而且易被還原為致癌性的芳香胺，因此它們的抗降解 性問題尤為棘手1 。環(huán)境保護署(EPA)已將這些物質列為有害物質，并 且認為它們會危害人體健康。 本應用紀要將探索如何應用CORTECS苯基色譜柱高效且有效地分離這 類化合物，并研究甲醇和乙腈對分離的影響。無論是對于節(jié)省成本 還是開發(fā)更出色的色譜方法而言，了解溶劑選擇對分析選擇性的影 響都具有重要意義。本研究將使用一種計算溶劑強度的方法展示乙 腈和甲醇在 CORTECS C8 色譜柱和CORTECS苯基色譜柱(2.7 μm填料)上的 選擇性差異2 。
