CORTECS C8柱是CORTECS家族的另一新成員。與典型C18柱相比，CORTECS C8柱的疏水保留性更低，因此有利于強疏水性化合物的分離與分析。CORTECS C8柱還適用于將常規(guī)C8柱HPLC方法轉(zhuǎn)換/升級到更耐用的色譜柱技術(shù)。
CORTECS C8柱的優(yōu)勢：
將常規(guī)C8柱HPLC方法轉(zhuǎn)換至更為穩(wěn)定耐用的色譜柱技術(shù)
與典型C18柱相比，疏水保留性較低
低pH條件下鍵合相穩(wěn)定
完全兼容LC-MS
使用CORTECS C8 色譜柱根據(jù)USP方法分析氯雷他定中的雜質(zhì)
政府監(jiān)管機構(gòu)要求制藥公司必須根據(jù)美國藥典(USP)中的標(biāo)準(zhǔn)對藥物 制劑化合物進(jìn)行分析。USP方法通常采用內(nèi)徑4.6 mm、填充顆粒直徑 在3 μm以上的大尺寸色譜柱，使得分析時間非常長，且流動相消耗 量非常大。 要想縮短運行時間，進(jìn)而縮短周轉(zhuǎn)時間和減少溶劑消耗量，方法之 一就是將原始USP方法轉(zhuǎn)換至填充有高柱效實心核顆粒的小尺寸色譜 柱1 ，而CORTECS色譜柱正是進(jìn)行這種方法革新之選。該系列色 譜柱采用了含有多種鍵合配體基團(tuán)的實心核顆粒，苯基和C8 填料是 CORTECS產(chǎn)品系列的最新成員。這些新的填料可分別用于革新USP指 導(dǎo)原則中使用L11和L7色譜柱的方法，能夠在不影響柱效的前提下縮 短運行時間。 在本應(yīng)用中，我們將分析氯雷他定中雜質(zhì)的USP方法分別轉(zhuǎn)換至三種 不同的色譜柱。方法轉(zhuǎn)換過程選用了3種不同粒徑的色譜柱，并以 USP通用章節(jié)<621>作為指導(dǎo)。
