CORTECS UPLC 1.6 µm實(shí)心核顆粒色譜柱是業(yè)內(nèi)性能。當(dāng)與低擴(kuò)散體積的UPLC系統(tǒng)使用時(shí)，它能夠提供別的柱效。與粒徑相當(dāng)?shù)娜嗫滋盍舷啾龋?/span>CORTECS UPLC 1.6 µm實(shí)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(shí)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(shí)現(xiàn)這個(gè)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(yàn)，采用超低擴(kuò)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(biāo)準(zhǔn)。
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(qiáng)度的流動(dòng)相(如甲酸)，對(duì)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(duì)在反相色譜中保留性能較差的強(qiáng)極性分析物進(jìn)行有效保留的模式。CORTECS HILIC色譜柱所含的未鍵合實(shí)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(dòng)相來(lái)保留極性分析物，HILIC則是使用含有高比例有機(jī)溶劑的流動(dòng)相實(shí)現(xiàn)對(duì)極性分析物的保留。
背景：在液相色譜分析中，如果樣品運(yùn)行過(guò)程 十分耗時(shí)，那么會(huì)由于對(duì)寶貴儀器的長(zhǎng) 時(shí)間占用和處理樣品數(shù)目的限制，導(dǎo)致 實(shí)驗(yàn)室整體工作效率降低。通過(guò)縮短樣 品分析時(shí)間來(lái)提高樣品通量是很困難的， 因?yàn)槌３Ｐ枰獱奚蛛x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(shí)提高樣品通量。
解決方案：高效的CORTECS UPLC色譜柱采用了的 實(shí)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(jìn)而縮短運(yùn)行時(shí)間并提高通量，而且無(wú)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(jìn)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(duì)梯度作 出相應(yīng)調(diào)整。
