5 Simple Techniques For use of hplc chromatography

With such stationary phases, retention time is for a longer time for lipophylic molecules, whereas polar molecules elute much more quickly (arise early from the analysis). A chromatographer can boost retention instances by incorporating much more water to your cellular phase, therefore making the interactions on the hydrophobic analyte While using
