Answer / yemulas(ycs)
the column selection is depends upon the polarity of the sample or drug
if in case the drug is highly polar choose highly non-polar column (c18,c8)
if in case the drug is low polar choose the low non-polar column (cyno,c4)
simple :--
sample polar then take --- non-polar column
sample non-polar then take ---polar column

phase.furthermore it also depends on the type of product
i.e. multiactive(more than one active),needs a better
resolution of peaks by increasing column lengh.
