An innovative solvent delivery method termed solvent modulation has been developed to control solute retention in liquid chromatography. Solvent modulation is the technique whereby individual solvent zones are introduced onto the chromatographic column in a known random or repeating sequence. Becaus
The stationary-phase capacity concepts derived from linear capacity are discussed in connection with the needs of analytical, trace enrichment analysis and preparative chromatography and shown to be unsuited to them. A new concept based on stationary-phase saturation and called "available capacity"
## Abstract Analytical equations for the capacity ratio in liquid adsorption chromatography with a binary mobile phase, involving soluteβsolvent and solventβsolvent association in the mobile and surface phases, have been derived. Very simple equations have been obtained for higher values of mole fr
