External mass transfer coefficients (k f ) were measured for a column packed with fully porous C 18 -silica spherical particles (50.6μm in diameter), eluted with a methanol/water mixture (70/30, v/v). The pulse response and the peak-parking methods were used. Profiles of elution peaks of alkylbenzene homologues were recorded at flow rates between 0.2 and 2.0mLmin −1 . Peak-parking...
