RP-HPLC gradient elution analysis for the determination of pantoprazole soldium and its related substances RP-HPLC梯度洗脱法测定泮托拉唑钠的有关物质及含量
Ascertainment of solvent elution system by TLC for component analysis of kiwifruit seeds 猕猴桃籽有机成分的薄层层析系统研究
MTc elution yield is an important quality parameter of 99mTc generator. 99mTc elution yield can be measured by the methods such as the quantitative analysis, the γ spectrometer analysis and the shield analysis. 99mTc发生器淋洗效率是评价其质量的重要指标,其效率可用定量加入法、γ能谱法和屏蔽法进行测量。
The sensitivity of elution curve to adsorption and transport coefficients, analyzed by Fourier analysis, was examined in a Single Pellet String Reactor ( SPSR) with the n-pentane-Pt-Sn/ Al2O3 system. 在珠串反应器上,使用Fourier分析的方法,考察了正戊烷-Pt-Sn/Al2O3体系的传递系数和吸附系数对流出峰影响的敏感性。
Two peaks were obtained in elution development. The result was checked up to be identical with that observed in ultracentrifuge analysis. According to the proteins contained, the percent recovery of subunit species was 91% in approximate estimation. 洗脱曲线呈现两个峰,其结果与样品超速离心分析结果一致,按蛋白质含量粗略计算,核糖体亚基回收率为91%。
Methods: The syringopicroside A was determined in GuangYanling Powder injection by HPLC gradient elution GuangYanling Powder injection analysis method. 方法:HPLC梯度洗脱方法测定广炎灵粉针中丁香苦苷A的含量。
Gradient elution mode was used to shorter the analysis time. 该方法采用了梯度洗脱缩短了分析时间。
Meanwhile on different elution and extraction solvent of allicin hydroxypropyl-β cyclodextrin entrapped complex closure rate mensuration analysis was studied and established the accurate closure rate determination methods. 同时对不同的洗脱和提取溶剂对大蒜素羟丙基-β-环糊精包合物包合率测定的影响进行了研究分析,确立了准确的包合率测定方法。
