產(chǎn)品簡介

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

詳細介紹

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)，方法開發(fā)和純化分離領(lǐng)域使用高pH值流動相。

§ XTerra顆粒能耐受二甲基亞砜（DMSO）溶劑，可延長高通量藥物發(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家在高pH值條件下，在純化堿性化合物時，一次進樣量增加六十倍。

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硅烷醇中有一個被替換成甲基基團。這個步驟只能在顆粒合成的起始階段完成，加入的此甲基基團是堿性顆粒骨架的組成部分。由此可生成機械強度大的顆粒，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)嵌極性基團的屏蔽技術(shù)與雜化顆粒技術(shù)結(jié)合起來，可以獲得對稱的色譜峰形。這一通用型色譜柱以的選擇性為快速方法開發(fā)提供了一個強有力的工具。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)秀的水浸潤性，即便是使用99%的水溶液作為流動相，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，是成功進行方法開發(fā)的工具。
