高效液相色谱法测定饮料中的苯甲酸、糖精钠、山梨酸

宣布日期：2016-06-30 点击次数： 62389

[摘要] 最终目标：创办并资料显示了用高效益色谱仪色谱法判断饮品中三类饮食营养加强剂的检侧体例；体例：敞开心扉液相色谱柱(XB-C18，4.6mm×250mm，5μm),0.02mol/L乙酸铵(pH约为6.0)-甲醇为勾当相（V/V=15/85），柱温30℃，空气流速1.0ml/min，检侧激发光谱230nm，以或然使用过程中定义，色谱峰占地面化学发光法；重大成就：该体例透亮收受打压率有98.59%～102.13%，或然要求数据误差RSD%为0.978％～1.254％，检侧限(S／N=3)为0.037～0.092mg.kg-1；论调：来尝试表示该体例对饮品中饮食营养加强剂的检侧飞速、简单明了、可操控性强。
如需大概物料，请商谈雇主做事中部：800-9993-800\400-7102-888。
