其符合美國藥典(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計,基質高度去活性,適合于在高水性流動相中使用,甚至能承受水相作為流動相,適合分析水溶性大,有機溶劑溶解性差的維生素和有機酸類物質。
其特定是能對大極性化合物(中性到弱酸性)有較強的保留能力和選擇性,幾乎*消除了色譜峰拖尾現(xiàn)象。非常適合于流動相中水相大于90%的場合,是水溶化合物和不易溶于有機相類化合的理性選擇。對于在水中有高度溶解性,而在有機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酸的分析。
采用了*的鍵合技術,減弱了由于硅羥基封閉不*而引起的色譜峰拖尾現(xiàn)象,使得色譜峰形對稱,分辨率加大。
能承受水相作流動相。
