Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection
spectrometric screening, X-ray powder diffraction and proton nuclear magnetic resonance (1 H- NMR). Chemometric analysis revealed that all manufacturers could be characterised based on the impurity, residual ...
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 ...
European fingerprint study on omeprazole drug substances using a multi analytical approach and chemometrics as a tool for the discrimination of manufacturing sources
proton nuclear magnetic resonance spectroscopy and X-ray powder diffractometry). The large amount of resulting analytical data were centralized and treated with two chemometric methods: Principal Component ...
