CORTECS UPLC 1.6 µm實心核顆粒色譜柱是業(yè)內(nèi)性能。當與低擴散體積的UPLC系統(tǒng)使用時,它能夠提供別的柱效。與粒徑相當?shù)娜嗫滋盍舷啾龋?/span>CORTECS UPLC 1.6 µm實心核顆粒柱可以給出更尖銳、更窄的色譜峰。到現(xiàn)在我們已經(jīng)發(fā)展出7種的CORTECS色譜柱鍵合相,包括從反相到HILIC柱,以便分離性質(zhì)不同的各種分析物。
與相似粒徑的全多孔顆粒相比,實心核顆粒因其形態(tài)特征的特殊性而更有可能獲得更高柱效。要實現(xiàn)這個理論柱效,還需要配合正確的色譜柱硬件和的柱裝填技術(shù)。沃特世憑借多年的UPLC柱生產(chǎn)經(jīng)驗,采用超低擴散的色譜柱硬件與柱裝填技術(shù),配合全新CORTECS顆粒,樹立了UPLC色譜柱柱效新標準。
基于2010年沃特世成功推出的表面帶電雜化顆粒技術(shù)(CSH™),為顆粒表面賦予少量正電荷,可以使用低離子強度的流動相(如甲酸),對堿性化合物以及肽仍能獲得的峰形與載量。
采用CORTECS HILIC色譜柱改善極性分析物的保留性能,親水作用色譜(HILIC)是一種對在反相色譜中保留性能較差的強極性分析物進行有效保留的模式。CORTECS HILIC色譜柱所含的未鍵合實心顆??梢员A魳O性化合物。在反相色譜中,通常采用高比例水相流動相來保留極性分析物,HILIC則是使用含有高比例有機溶劑的流動相實現(xiàn)對極性分析物的保留。
利用CORTECS UPLC色譜柱提高樣品通量
背景:在液相色譜分析中,如果樣品運行過程 十分耗時,那么會由于對寶貴儀器的長 時間占用和處理樣品數(shù)目的限制,導致 實驗室整體工作效率降低。通過縮短樣 品分析時間來提高樣品通量是很困難的, 因為常常需要犧牲分離度或靈敏度等重 要色譜屬性。然而,采用CORTECS UPLC色譜柱就可以在保持峰容量的同時提高樣品通量。
解決方案:高效的CORTECS UPLC色譜柱采用了的 實心核顆粒和填充技術(shù),能夠在高流速 下保持良好的分離性能。這讓色譜工作 者可以根據(jù)需要提高方法的流速,進而縮短運行時間并提高通量,而且無需犧 牲分離質(zhì)量。圖1所示為使用 CORTECS UPLC C18 +色譜柱分析磺胺類藥物,并使用 全多孔C18色譜柱進行初始分離的結(jié)果比 較。CORTECS UPLC C18+色譜柱流速為初始 分離的兩倍,并按照流速變化對梯度作 出相應(yīng)調(diào)整。
