First take ir of that sample and judge the functional
goroups attached to that compound and also structure of
that compound.
then check solubility.
then UV scan with known concentration and find lymda max.
then selection of column.
first try with regular solvent like water, acn,
methanol.and then go to the buffers of different pH.near to
its pka value.
also different coloumn.
