Title: non-ideal, non-linear chromatography Long Title: IUPAC Gold Book - non-ideal, non-linear chromatography DOI: 10.1351/goldbook.NT06945 Status: current Definition Chromatographic process, where both isotherm curvature and other peak-broadening processes (such as diffusion) contribute to the peak shape. Note This case comprises most peaks in common practice that are characterised as 'tailing' or 'fronting'.
