Pressure Liquid Dietary Supplements Discriminant Analysis Least-Squares Analysis Plants Abstract: The popularity of plant food supplements has seen explosive growth all over the world, making them ...
Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection
falsified samples. In total, 46 tadalafil API samples from 13 different manufacturers were collected. For all samples fingerprint data was collected through analysis of impurities and residual solvents, mass ...
Contents of Amoxicillin Drugs Dispensed in Goma, Democratic Republic of Congo
drugs, but all samples contained the active ingredients as claimed on the packages. We found under dosage of 90% and less in 3 of the 15 amoxicillin samples and in none of the 9 combined specimens. ...
GEONs API fingerprint project: Selection of analytical techniques for clustering of sildenafil citrate API samples
chromatography for residual solvents, X-ray diffraction and Nuclear Magnetic Resonance (NMR) spectroscopy. Chemometrics applied to the collected data showed that all manufacturers could be discriminated based on ...
The occurrence of non-anatomical therapeutic chemical-international nonproprietary name molecules in suspected illegal or illegally traded health products in Europe: A retrospective and prospective study.
collected from the illegal market, while only 3% originated from a legal source. For the rest of the samples, categorisation was not possible. Moreover, 69% of all the reported samples were presented as ...
Impurity profiling of the most frequently encountered falsified polypeptide drugs on the Belgian market
drugs. Subsequent speciation of As confirmed the elevated concentrations for As and demonstrated that all As was present in the more toxic inorganic form. Together with the (sometimes) high amount of ...
A simple dilute and shoot methodology for the identification and quantification of illegal insulin
approach is not only able to distinguish between all those different versions of insulin and the insulins originating from different species, but also able to chromatographically separate human insulin and ...
