Abstract
This paper presents the development of
chromatography, two mathematical methods for describing
chromatographic phenomena, band broadening processes as well as
the procedure for retention volume measurement and calculation. The
plate and the rate theories for gas chromatographic phenomena are
comprehensively discussed. The reduction of infinite dilution activity
coefficients from retention data is explained. While the rate theory
can predict the influence of various factors on column performance,
the plate theory is more useful in the calculation of thermodynamic
properties such as infinite dilution activity coefficients, enthalpy and
entropy of mixtures.
