Question

A polar compound is gas chromatographed on a non-polar SE-1capillary column and then on a highly polar Carbowax 20M column,both of identical length, diameter, staionary phase thickness,mobile phase flow rates, and temperatures.

A) How will the distribution ratio for the solute differ betweenthe stationary and mobile phase for the two columns (K - [conc]stationary phase / [conc] mobile phase) ?

B) In which column will the solute spend less time in the mobilephase?
