The liquid chromatography packing, such as C18 silica, it is quite common.

But are you able to choose the right chromatography packing? 

According to the solubility, if it is water insoluble, and it is non-polar or weak polar, you can choose Si, NH2, Diol. If it is weak polar to mid-polar, you can choose C18, C8, C4, CN, Diol, NH2, Phenyl. If it is mid-polar to strong-polar, you can choose C18, C8.
