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 ...
Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.
chemometrics was evaluated for the discrimination between nicotine containing and non-nicotine containing samples. It could be concluded that both ATR- IR and NIR could be used for the discrimination when ...
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.
evaluation of suspected samples. This study proposes a combination of ATR- FTIR and chemometrics to discriminate and classify counterfeit medicines. A sample set, containing 209 samples in total, was analyzed ...
Detection of sibutramine in adulterated dietary supplements using attenuated total reflectance-infrared spectroscopy.
adulterated dietary supplements. Data interpretation was performed using different basic chemometric techniques. It was found that the use of ATR- IR combined with the k-Nearest Neighbours (k- NN) was able to ...
Detection of whitening agents in illegal cosmetics using attenuated total reflectance-infrared spectroscopy.
attenuated total reflectance-infrared (ATR- IR) spectroscopy, combined with chemometrics, was evaluated for that purpose. It was found that the combination of ATR- IR with the simple chemometric technique ...
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 ...
Chemometrics and chromatographic fingerprints to discriminate and classify counterfeit medicines containing PDE-5 inhibitors.
chemometric techniques were applied to reveal structures in the data sets as well as differences among the samples. The focus was on the differentiation between genuine and counterfeit samples and on the ...
Classification trees based on infrared spectroscopic data to discriminate between genuine and counterfeit medicines
Publication Type: Scientific poster, presentation or proceeding Authors: Eric Deconinck; P.Y. Sacré; Coomans,D.; J. De Beer Source: Chemometrics In Analytical Chemistry 2012, NA, Issue Hungarian ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
1 (2024) Keywords: e-liquids; spectroscopic techniques; chemometric techniques; data analysis Abstract: Vaping electronic cigarettes (e-cigarettes) has become a popular alternative to smoking tobacco. When ...
