3.
The five stable chromatographic peaks have been found in all the measured chromatograms,which have the same or extremely close relative retention time and which should be used as the good qualitative character of the fingerprint.
发现了5个色谱峰能够较为稳定地出现在所测样本的色谱图中,它们表现出了相同或极其相近的相对保留时间,因此可以作为指纹谱图的良好的定性特征。
3)  retention time
保留时间
1.
RP-HPLC method for calibrating the error of retention time of MTX;
RP-HPLC进行甲氨蝶呤血药浓度监测时保留时间校准方法研究
2.
Experiments showed that retention time of aniline was shortened with the increase of the concentration of methanol and chromatogram was improved along with the change of pH by the choice of suitable separated conditions,the optimum concentration of methanol was 30% and the optimum pH was 4.
应用HPLC法对等离子体降解联苯胺的中间产物进行了分析,在254nm下检测到了对氨基苯酚,苯胺,联苯胺,苯酚,甲酸,草酸和丙二酸等中间产物;通过分离条件的优化选择,表明流动相中甲醇的比例增大,苯胺的保留时间明显缩短,峰形改善。

CAS号:

性质:溶质通过色谱柱所需时间,即待测组分从进样到出现峰最大值所需的时间。保留时间是由色谱过程中的热力学因素所决定的,在一定色谱体系和特定色谱操作条件下,任何一种化合物都有一个确定的保留时间,是色谱定性分析的依据。
