Refractive Index Detector Refractive index (RI) detection is a cost-effective solution recommended for routine analysis of non-UV absorbing compounds. It is an excellent choice for the analysis of sugars, polymers, surfactants and other compounds that do not contain a chromo...
一、化药 使用反相固相萃取柱的Online SPE-HPLC应用案例：以复方甘草片中的吗啡成分测试为例，在2020版药典中吗啡含量测定需要进行离线固相萃取，操作流程繁琐，耗时较长，且易造成目标成分的损失，将该前处理方法转换成Online SPE方法，即可实现快速、高效的富集与净化，并直接转入分析色谱柱，取得更准确的含量测定结果。
Universal detection independent of chemical structure with a near-uniform response for non-volatile and many semi-volatile analytes. Diode Array Detector (DAD), also known as Photodiode Array (PDA) Detector Analyte must contain a chromophore. Acquire UV-Vis spectra in multiple channels and a 3D...

论文标题: HPLC-UV法测定大鼠脑组织中利培酮的含量 英文标题: 中文摘要: 目的:建立大鼠脑组织中利培酮含量的测定方法。方法:取大鼠,ig 30 mg/kg的利培酮混悬液,30 min后断头处死,分离脑组织;采用高效液相色谱-紫外法,以盐酸小檗碱为内标,测定大鼠脑组织中利培酮的浓度。色谱条件采用色谱柱Wondasil C18(250 mm×...
The samples were extracted with hexane/ethyl acetate (95/5, v/v) by a dry column procedure, and the eluate was analyzed by HPLC with UV detection. Recoveries ranged from 91–102% for the individual components and from 93–100% for mixtures. The improved method requires less analysis time ...
