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 ...
Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.
also a fraction of (nano)particles. Energy-dispersive X-ray spectroscopy (EDX) and electron diffraction confirmed that the (nano)particles and micrometre-sized flakes consisted of silver. A higher amount ...

thresholding and constituent particle detection. The large majority of constituent particles, confirmed to be TiO2 by energy dispersive X-ray spectroscopy (EDX), were reliably detected and measured by the ...
Physicochemical Characterisation of the E171 Food Additive
X-ray spectroscopy (EDX), were reliably detected and measured using the ParticleSizer software. In the most dispersed state, the particle size measurements by TEM and sp- ICP- MS agreed well. The ...
Physical Characterization of Nanomaterials in Dispersion by Transmission Electron Microscopy in a Regulatory Framework
specimens to obtain a representative distribution of particles on the grid is discussed. The application of TEM imaging methods, electron diffraction and analytical TEM to obtain complementary information on ...
