Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.
the products is not always labelled, especially when they are bought through internet. Therefore there is a need for easy-to-use equipment and methods to perform a first on site screening of intercepted ...
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.
based on the Monte Carlo approach that is used in the context of authenticity studies based on chromatographic impurity profiles. The performance of the validation approach was applied to evaluate the ...
Comparison of three development approaches for Stationary Phase Optimised Selectivity Liquid Chromatography based screening methods Part II: A group of structural analogues (PDE-5 inhibitors in food supplements).
adulterated dietary supplements, based on Stationary Phase Optimised Selectivity Liquid Chromatography were compared for their easiness/speed of development and the performance of the optimal method obtained. ...
Comparison of three development approaches for Stationary Phase Optimised Selectivity Liquid Chromatography based screening methods Part I: A heterogeneous group of molecules (slimming agents in food supplements).
detect adulterated dietary supplement, based on Stationary Phase Optimised Selectivity Liquid Chromatography were compared for their easiness/speed of development and the performance of the optimal method ...
Testing of complementarity of PDA and MS detectors using chromatographic fingerprinting of genuine and counterfeit samples containing sildenafil citrate.
a very important issue. In this study, a high-performance liquid chromatography-photodiode array (HPLC- PDA) and high-performance liquid chromatography-mass spectrometry (HPLC- MS) method were developed ...
Relation between Spongy Bone Density in the Maxilla and Skeletal Bone Density.
group B (healthy, control), and group C (osteopenia) on the basis of a dual-energy x-ray absorptiomery (DXA) scan. These patients also received a CT scan on which bone density measurements were performed ...
First Belgian national EQA for special stains in histopathology
the secondsurvey (2015) for special stains in histopathology.Aim:The two surveys aimed at assessing laboratory and method performance of the Belgian licensed pathologylaboratories. General quality of ...
Evolution of the implementation of a quality management system in the Belgian laboratories for anatomic pathology
Quality of Medical Laboratories at the IPH has been performed. Methods In 2014, in collaboration with the Commission of Anatomic Pathology, all licensed laboratories were asked to fill out a table in ...
Analysis of illegal peptide biopharmaceuticals frequently encountered by controlling agencies.
MS / MS) for the identification of counterfeit and illegal injectable peptide preparations, extended with a subsequent quantification method using ultra-high performance liquid chromatography with ...
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 ...
