Abstract

The mass-transfer properties of a core-shell packing material with 1.6 μm particle diameter, and that of a fully porous packing material with 1.7 μm particle diameter were investigated and compared. The first absolute and the second central moments of the peaks of the homologous series of alkylbenzenes, over a wide range of mobile phase velocities were measured and used for the calculation of the mass-transfer coefficients. For the evaluation of the band broadening caused by the thermal dissimilarities, the measurements were carried out under thermostated conditions and also at near adiabatic insulation of the columns.
