Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
classifier (kNN). Both MS1 and MS2 data and data measured at 254 nm and 270 nm were used with the aim to test the potential complementarity of PDA and MS detection. First, it was checked if both groups of ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
profiling and IR spectroscopy to obtain a prime discrimination between genuine and counterfeit Viagra® and Cialis® medicines. Hypothesis testing showed that most illegal samples differ significantly from ...
The Monte Carlo validation framework for the discriminant partial least squares model extended with variable selection methods applied to authenticity studies of Viagra® based on chromatographic impurity profiles.
usefulness of the diagnostic logic rule obtained from the partial least squares discriminant model (PLS- DA) that was built to discriminate authentic Viagra® samples from counterfeits (a two-class problem). ...
