其符合美國(guó)藥典（USP）L1方法要求。屬于反向色譜，*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)。

其特點(diǎn)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，幾乎完全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。

采用了先進(jìn)的鍵合技術(shù)，減弱了由于硅羥基封閉不完全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。
