portant; overflow-wrap: break-word !important;">      绿原酸是中苍耳子的主要成分,虽然苍耳子是一种较为常见的药材,但是在中国药典(2020版)液相检测中,修改了苍耳子含量测定方法,使用的色谱柱也由苯基柱调整为十八烷基硅烷键合硅胶柱。     

portant; overflow-wrap: break-word !important;">     喆分色谱在实验过程中经过不断的努力尝试,筛选出适合的色谱柱——Zafex Supfex ZY-C18(250*4.6mm,5um),该色谱柱是一款特价柱,并且具备广泛的品种适应性,依靠其出色的性价比,目前多家药企已将该款色谱柱作为中药饮片通用柱使用,市场反响好评不断。
