With respect to liquid column chromatography in which the stationary phase is silica, propose a suitable strategy for separating two components of a binary mixture that fail to move when hexane is the mobile phase and move the same distance when methanol is the mobile phase. Explain your reasoning.

Which phase carries the analyte through the Chromatographic separation? Standard Phase, Detection Phase ,Injection Phase, Stationary Phase, Mobile Phase Which phase slows the analyte down in the Chromatographic separation? Standard Phase, Detection Phase ,Injection Phase, Stationary Phase , Mobile Phase If you increase the flow rate of the mobile phase, will the analyte come out ________? Slower, In two Peaks, Faster, Unchanged In this separation the stationary phase is polar and the mobile phase is non-polar. Youre separating two molecules,...

1. Besides silica and alumina, can any other stationary phases be utilized for the separation of chlorophylls? 2. Predict the order of compounds on a TLC for the b-carotene, chlorophyll a and b, and cryptoxanthin pigments found in spinach. Also, predict the order of elution from the column. Explain/justify your answer with polarity arguments.

What are the surface functional groups on the stationary phase in normal phase LC and reverse phase LC. Write out the eluotropic series for both normal phase LC and reverse phase LC using the common solvents we discussed in class (acetonitrile, MeOH, diethylether, H2O, pentane, toluene). Why acetonitrile is a stronger eluting solvent than toluene in normal phase LC?
