ATR-FTIR spectroscopy and chemometrics: An interesting tool to discriminate and characterize counterfeit medicines.
different API s. However k- NN performs the least while SIMCA performs the best. Secondly, it was tested whether these three models could be expanded to discriminate between genuine and counterfeit samples as ...
In vitro Dermal Absorption: Sample Application and Seal Quality in a Franz Diffusion Cell System.
Consumer Safety (SCCS) have published guidance documents of how to perform these in vitro tests. For the parameter ‘sample application’ and ‘adequate seal’, it is indicated to apply the sample homogeneously ...
Application of the characteristic function to evaluate and compare analytical variability in an external quality assessment scheme for serum ethanol.
analysis Abstract: BACKGROUND: As a cornerstone of quality management in the laboratory, External Quality Assessment (EQA) schemes are used to assess laboratory and analytical method performance. The ...
Development of a Stationary Phase Optimised Selectivity Liquid Chromatography based screening method for adulterations of food supplements for the treatment of pain.
the screening to be performed with diode array detection and is fully compatible with mass spectrometry. The method was validated for its selectivity following the guidelines as described for the ...

Accuracy of linear measurements using three imaging modalities: two lateral cephalograms and one 3D model from CBCT data.
twice by two observers with a 4 week interval. Direct physical measurements by a digital calliper were defined as the gold standard. Statistical analysis was performed. RESULTS: Nasion-Point A was ...
HS-GC-MS method for the analysis of fragrance allergens in complex cosmetic matrices.
ingredients list to prevent elicitation of an allergic reaction. It is therefore important to quantify potential allergenic ingredients in cosmetic products. An easy to perform liquid extraction was developed, ...
Detection of sibutramine in adulterated dietary supplements using attenuated total reflectance-infrared spectroscopy.
a need for easy to use equipment and techniques to perform an initial screening of samples. Attenuated total reflectance-infrared (ATR- IR) spectroscopy was evaluated for the detection of sibutramine in ...
Detection of whitening agents in illegal cosmetics using attenuated total reflectance-infrared spectroscopy.
misleading packaging and the existence of products containing only legal components. Therefore there is a need for easy to use equipment and techniques to perform an initial screening of samples. The use of ...
Physical profiling and IR spectroscopy: simple and effective methods to discriminate between genuine and counterfeit samples of Viagra® and Cialis®.
99.42% for Cialis®). Moreover, CART confirmed the observation that mass and long length are the key physical characteristics which determine the observed discrimination. IR analysis was performed on ...
