What is the Difference Between Packed Column and Capillary .

Oct 18, 2018 · The main difference between packed column and capillary column is that, in a packed column, the stationary phase is packed into the cavity of the column whereas, in a capillary column, the stationary phase coats the inner surface of the cavity of the column. Furthermore, we mainly use packed columns in liquid-liquid extractions and capillary columns in gas chromatography.

A packed column is a pressure vessel that has a packed section. The column can be filled with random dumped packing or structured packing sections, which are arranged or stacked. In the column, liquids tend to wet the surface of the packing and the vapors pass across this wetted surface, where mass transfer takes place.
