Characterization of suspected dermal fillers containing hyaluronic acid
fillers intercepted in 2016 were assessed. All legal samples and 2 out of 14 suspected illegal samples were conform for the amount of HA claimed and present in the sample. Most of the suspected illegal ...

An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
concerns and hence there is a need for highly sensitive profiling of residual plasma source proteins. This study aims to consider LC- ESI- QTOF data-dependent acquisition in combination with sample ...

Chemometrics and the identification of counterfeit medicines-A review.
the major emphasis on the most frequently selected instrumental techniques to characterize drug samples and the chemometric methods being used to explore and/or model the analytical data. However, ...
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 ...
In vitro Dermal Absorption of Hydroquinone: Protocol Validation and Applicability on Illegal Skin-Whitening Cosmetics.
used to determine the dermal absorption of illegal skin-whitening cosmetics containing hydroquinone. All samples gave high dermal absorption values, rendering them all unsafe for human health. These ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
on PDE-5 Inhibitors. Both physical and chemical properties of these samples were taken into consideration to discriminate counterfeit medicines from genuine ones. Chapter V focuses on physical ...
Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.

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). ...
