Parameterisation of symmetrical peaks in capillary electrophoresis using [3/2]-type rational approximants

摘要

The peaks in data from electrophoresis are parameterised in terms of a resonance model. The method we describe is based on forming a rational interpolant to the data. The interpolant is converted to a resonance approximation for symmetrical peaks; the method is found to discriminate successfully against formation of a resonance approximations to asymmetrical peaks. The method would also apply to equally good quality data from GC, LC and NMR.
