The absorption spectra of electrophoretic peaks of the sample were
monitorated simultaneously during the analysis of the pharmaceutical
sample without the addition of strontium ranelate and aspartame standards.
Identification of the strontium ranelate and aspartame peakswas
confirmed by wavelength of maximum absorption at 235 nm and
198 nm, respectively, which demonstrated the ability and selectivity
of the method to identify the analytes of interest in the pharmaceutical
formulation, even in the presence of other substances (maltodextrin
and mannitol) in the sample matrix.
