A polar compound is gas chromatographed on a non-polar SE-1 capillary column as well as then on a highly polar Carbowax 20M column both of identical length, diameter, stationary phase thickness, mobile phase flow rates, and temperatures.
A) How will the distribution ratio for the solute be different between the stationary and mobile phase for the two columns (K - [conc] stationary phase / [conc] mobile phase)?
B) Explain in which column will the solute spend less time in the mobile phase?
