Gradient elution in liquid chromatograph

Gradient elution in liquid chromatography : IV. Verification of the theoretical relationships for elution characteristics (retention volume, band width, resolution, plate number) in adsorption chromatography on silica using stepwise and combined (stepwise—gradient) elution and some considerations concerning solvent-programmed and isocratic elution chromatography

The verification of the theoretical equations for the elution characteristics in stepwise and combined two-step isocratic-gradient elution chromatography is described for four N,N-dimethyl-p-aminobenzeneazobenzoyl amides chromatographed on Porasil A using a binary mobile phase consisting of ethyl ac
