Answer / m.sivalingeswara rao

Elution Order depedands on the polarity of the compound and
with the type of chromatography.Again ,If you choose
Reverse phase/normal phase chromatography, mobile phase
composition ,stationery phase, column oven temperature will
also play key role in deciding the elution order as well as
separation.
