Capacitively coupled contactless conductivity detection to account for system-induced gradient deformation in liquid chromatography

Publikováno v: Analytica Chimica Acta. 1271:1-12

The time required for method development in gradient-elution liquid chromatography (LC) may be reduced by using an empirical modelling approach to describe and predict analyte retention and peak width. However, prediction accuracy is impaired by syst
