CORTECS苯基柱是CORTECS色譜柱家族的新成員，為CORTECS C18柱提供互補(bǔ)的選擇性。基于的pi-pi作用，苯基柱能夠?yàn)榉枷慊衔锾峁┑倪x擇性。使用質(zhì)子性溶劑如甲醇，能夠進(jìn)一步增強(qiáng)pi-pi作用。
CORTECS苯基柱的優(yōu)勢(shì)：
與典型C18鍵合相相比，為芳香化合物提供互補(bǔ)選擇性
低pH條件下鍵合相穩(wěn)定無(wú)流失
兼容LC-MS
CORTECS苯基色譜柱對(duì)硝基芳香化合物分離的選擇性
硝基芳香化合物幾乎不會(huì)在自然界中自發(fā)形成，它們主要通過(guò)人工合 成，染料、聚合物、殺蟲(chóng)劑和中都含有該類(lèi)物質(zhì)。大規(guī)模地合成 此類(lèi)化合物會(huì)造成土壤和地表水污染，最終引發(fā)環(huán)境問(wèn)題。硝基賦予 了此類(lèi)分子多樣的化學(xué)性質(zhì)和功能，但也導(dǎo)致這些物質(zhì)難以進(jìn)行生物 降解。由于這類(lèi)物質(zhì)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(wèn)題尤為棘手1 。環(huán)境保護(hù)署(EPA)已將這些物質(zhì)列為有害物質(zhì)，并 且認(rèn)為它們會(huì)危害人體健康。 本應(yīng)用紀(jì)要將探索如何應(yīng)用CORTECS苯基色譜柱高效且有效地分離這 類(lèi)化合物，并研究甲醇和乙腈對(duì)分離的影響。無(wú)論是對(duì)于節(jié)省成本 還是開(kāi)發(fā)更出色的色譜方法而言，了解溶劑選擇對(duì)分析選擇性的影 響都具有重要意義。本研究將使用一種計(jì)算溶劑強(qiáng)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 。
