## Abstract In capillary gasβsolid chromatography where interactions between solute and carrier gas and adsorption of the solute on the surface of the adsorbent are considered to be imperfect, it has been shown that chromatographic retention is determined largely by adsorption processes. It has bee
## Abstract The promising technique of controlling chromatographic selectivity by the adjustment of individual column temperatures in systems of seriesβcoupled columns is investigated by means of a general model incorporating the effects of temperature and mobile phase compressibility. Expressions
For a typical narrow bore (50 pm) and wide bore (320 Fm) capillary column the effects of increased stationary phase film thickness (df) on the minimum detectable amount, Q, , as well as on the minimum analyte concentration, C , , are described. In treating the effect of an increased film thickness,
