Ultra Aqueous C18 液相色譜柱(USP L1)


粒徑(μm):3、5,球型

孔徑(A):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計,基質(zhì)高度去活性,適合于在高水性流動相中使用,甚至能承受100%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(zhì)。 

其特點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,幾乎完全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。

采用了先進的鍵合技術,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,使得色譜峰形對稱,分辨率加大。

能承受100%水相作流動相。
