Label for mobile phase
WebThe term HILIC is just one word for plenty of solute-stationary phase-mobile phase interactions. ... retention with respect to the increase in the organic phase in water, people label it as a ... WebThese numbers indicate whether the analyte (solute) prefers the stationary or mobile phase. With stationary and mobile phases, R f values are used to determine polarity, relative masses, and relative solubilities, among other things. When comparing the results of one chromatogram to those of another, retention factors come in handy.
