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 ...
Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
in water as the loading solution, 50% methanol in water as the washing solvent, and 5 ml of methanol as the elution solvent yielded the optimal purification efficiencies. The established method was ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers.
solvent-assisted flavor evaporation (SAFE) technique coupled to GC- MS (SIM) was developed and validated. Focus was put on authorized flavoring substances requiring specific attention due to a genotoxic concern ...
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
analysis carried out by 7 European laboratories on 28 samples from 11 manufacturers with 5 analytical techniques (related substances with HPLC, residual solvents with GC- MS, near infrared spectroscopy, ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers
a wide range of compounds in various types of food and drinks. In order to improve the monitoring of flavoring substances, a versatile and accurate analytical method using the solvent-assisted flavor ...
All in one method for the analysis of multiclass food additives using UHPLC-MS/MS
in Europe. A QuEChERS based extraction has been devised using acidified acetonitrile as extraction solvent, followed by a C18 and PSA dispersive solid phase extraction step. For the development of the ...
