Clustering and diagnostic modelling of slimming aids based on chromatographic and mass spectrometric fingerprints
highly informative fingerprints. Three types of fingerprints were acquired (PDA, Total Ion Chromatograms (TIC), and MS fingerprints) which were used in the chemometric data analysis. Both unsupervised ...
Complementarity of PDA and MS detection for chromatographic fingerprinting of genuine and counterfeit Viagra
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 ...
Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
were developed to analyse both genuine and counterfeit samples of Cialis®. The obtained PDA and MS fingerprints were explored and modelled using unsupervised Principal Component Analysis (PCA) and ...
Study of the possible migration risks of food contact materials for children under 3 years
performed individually, and that the combination thereof might result in a higher release. Chapter 5.3 presents the results of a fingerprinting study that was made on the initial samples and on those exposed ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
Publication Type: Dissertation Authors: Custers, Deborah Source: UAntwerpen, Antwerp, Belgium, p.291 (2016) Accession Number: NA Keywords: Chemometrics Counterfeit medicines detection fingerprint ...
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, ...
ATR-FTIR spectroscopy and chemometrics: An interesting tool to discriminate and characterize counterfeit medicines.
using ATR- FTIR and the obtained spectra were used as fingerprints in the chemometric data-analysis which included Principal Component Analysis (PCA), k-Nearest Neighbours (k- NN), Classification and ...
Identification of (antioxidative) plants in herbal pharmaceutical preparations and dietary supplements.
synthetic origin. This chapter describes a strategy for the fast development of a chromatographic fingerprint approach that allows the identification of a targeted plant in herbal preparations and dietary ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
components, like residual solvents, becomes more important. Assessment of residual solvent content and chemometric analysis of fingerprints might be useful in the discrimination between genuine and counterfeit ...
Towards a typing strategy for Arcobacter species isolated from humans and animals and assessment of the in vitro genomic stability.
species. With a limited number of isolates to be characterized, PFGE with restriction by KpnI is proposed as the first method of choice. However, ERIC- PCR represents a more convenient genomic fingerprinting ...
