Ultra Aqueous C18 Columns (USP L1)
粒徑(μm):3、5,球型
孔徑(?):100
碳載量(%):15
封尾:否
PH范圍:2.5 - 8
溫度上限(°C):80
相似固定相:AQUA C18, Aquasil C18, Hypersil Gold AQ, YMC ODS-Aq
其符合美國(guó)藥典(USP)L1方法要求。屬于反向色譜,專為分析極性大的化合物而設(shè)計(jì),基質(zhì)高度去活性,適合于在高水性流動(dòng)相中使用,甚至能承受100%水相作為流動(dòng)相,適合分析水溶性大,有機(jī)溶劑溶解性差的維生素和有機(jī)酸類物質(zhì)。
其特定是能對(duì)大極性化合物(中性到弱酸性)有較強(qiáng)的保留能力和選擇性,幾乎*消除了色譜峰拖尾現(xiàn)象。非常適合于流動(dòng)相中水相大于90%的場(chǎng)合,是水溶化合物和不易溶于有機(jī)相類化合的理性選擇。對(duì)于在水中有高度溶解性,而在有機(jī)溶劑只有低溶解性的化合物,該固定相有*的使用性能。例如用于水溶性的維他命和有機(jī)酸的分析。
¨ 采用了優(yōu)良的鍵合技術(shù),減弱了由于硅羥基封閉不*而引起的色譜峰拖尾現(xiàn)象,使得色譜峰形對(duì)稱,分辨率加大。
能承受100%水相作流動(dòng)相。
