Publication Type: Scientific poster, presentation or proceeding Authors: Custers,D. Source: the Great Scientific Exchange (SCIX) 2016, NA, Issue the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS), NA (2016) Keywords: Counterfeit det ...
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). ...
Testing of complementarity of PDA and MS detectors using chromatographic fingerprinting of genuine and counterfeit samples containing sildenafil citrate.
for the analysis of genuine Viagra®, generic products of Viagra®, and counterfeit samples in order to obtain different types of fingerprints. These data were included in the chemometric data analysis, ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
Viagra(®) and Cialis(®) samples were analyzed for residual solvent content using headspace- GC- MS. The obtained chromatograms were used as fingerprints and analyzed using different chemometric techniques: ...
Chemometrics and chromatographic fingerprints to discriminate and classify counterfeit medicines containing PDE-5 inhibitors.
genuine and counterfeit samples of Viagra(®) and Cialis(®) were evaluated for their use in the detection and classification of counterfeit samples of these groups of medicines. Therefore several exploratory ...
