The effects of column outlet pressures on the HETP <I>vs</I>. carrier gas velocity curves are discussed on the basis of KOS theory. It is shown that when a column is operated at a constant outlet pressure higher than atmospheric the minimum of <I>H</I>-\bar<I>u</I> curve shifts towards lower HETP and \bar<I>u</I> values, and on the contrary the operation at reduced outlet pressure results in the shift of the minimum towards higher HETP and \bar<I>u</I> values. The separation factor and number of theoretical plates obtained by a column operated at the outlet pressure of 4.0 atm are superior by <I>ca.</I> 10% to those obtained by normal gas chromatography.
