With these types of stationary phases, retention time is longer for lipophylic molecules, Whilst polar molecules elute additional commonly (arise early while in the analysis). A chromatographer can enhance retention situations by including extra water for the cell period, thus making the interactions in the hydrophobic analyte Together with the hyd… Read More
