能耐受二甲基亞砜（DMSO）溶劑，在純化堿性化合物時(shí)，一次進(jìn)樣量增加六十倍。

詳細(xì)介紹

基于代雜化顆粒技術(shù)的 XTerra® 系列高效液相色譜柱, 可以讓色譜工作者在藥物發(fā)現(xiàn)，方法開(kāi)發(fā)和純化分離領(lǐng)域使用高pH值流動(dòng)相。

§ XTerra顆粒能耐受二甲基亞砜（DMSO）溶劑，可延長(zhǎng)高通量藥物發(fā)現(xiàn)研究中色譜柱的壽命。

§ 寬pH 范圍使得方法開(kāi)發(fā)研究人員在所需的pH值條件下操作，以獲得性。

§ 高載荷量使得分離純化的科學(xué)家在高pH值條件下，在純化堿性化合物時(shí)，一次進(jìn)樣量增加六十倍。

XTerra® MS、Shield RP和苯基色譜柱將硅膠和聚合物鍵合相的性能與的雜化顆粒技術(shù)相結(jié)合，在顆粒合成中每三個(gè)硅烷醇中有一個(gè)被替換成甲基基團(tuán)。這個(gè)步驟只能在顆粒合成的起始階段完成，加入的此甲基基團(tuán)是堿性顆粒骨架的組成部分。由此可生成機(jī)械強(qiáng)度大的顆粒，適用于高pH值條件下的分離，提高堿性化合物的上樣量和峰形。

XTerra® RP18和RP8色譜柱將內(nèi)嵌極性基團(tuán)的屏蔽技術(shù)與雜化顆粒技術(shù)結(jié)合起來(lái)，可以獲得對(duì)稱(chēng)的色譜峰形。這一通用型色譜柱以的選擇性為快速方法開(kāi)發(fā)提供了一個(gè)強(qiáng)有力的工具。同其它所有XTerra® 色譜柱一樣，利用屏蔽技術(shù)的XTerra® RP色譜柱展現(xiàn)了極其優(yōu)秀的水浸潤(rùn)性，即便是使用99%的水溶液作為流動(dòng)相，亦可獲得穩(wěn)定的色譜結(jié)果。大大拓寬的pH范圍，為選擇性調(diào)節(jié)提供了有效途徑；加上選擇性互補(bǔ)的MS和RP兩種鍵合相更是增加了選擇性的調(diào)節(jié)范圍，是成功進(jìn)行方法開(kāi)發(fā)的工具。
