Chromatographic fingerprint development for the detection of tobacco varieties in commercial tobacco products
development, various parameters were tested and optimized, including the pH and organic component of the mobile phase, the gradient, column type and the influence of different extraction solvents. After ...
Occurrence and Synthesis Pathways of (Suspected) Genotoxic α,β-Unsaturated Carbonyls in Chocolate and Other Commercial Sweet Snacks.
solvent-assisted flavor evaporation (SAFE) coupled to GC- MS / SIM. Monitored α,β-unsaturated aldehydes were formed during chocolate production, primarily through aldol condensation of Strecker aldehydes triggered ...
Occurrence and Synthesis Pathways of (Suspected) Genotoxic α,β-Unsaturated Carbonyls in Chocolate and Other Commercial Sweet Snacks
Ten of them (either commercially available or synthesized here by combinatorial chemistry) were first investigated throughout the chocolate-making process by solvent-assisted flavor evaporation (SAFE) ...
Characterisation and Hazard identification of substandard and Falsified Antimicrobial Drugs. The CantiBio project 2016-2020
demonstrated based on f 1 and f 2 statistics. Finally a series of tests of microbiological contamination, residual solvents and heavy metals were carried out. The results showed that 35% of samples did not ...
Handbook of Solvents volume II, Use, Health and Environment
Publication Type: Scientific book or chapter Authors: Eric Deconinck; Bart Desmedt Source: Residual solvents in pharmaceutical substances and products, Volume 2, Issue 14.2, Number 1322, p.28 (2024) ...
Screening the capability of vibrational spectroscopic techniques for simultaneous quantification of vitamins B1, B6, and B12 in a powder blend
solvents or reagents in sample preparation, FTIR, NIR and Raman spectroscopy belong to the group of environmentally friendly techniques, known as “green analytical techniques”. Such characteristics ...
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 ...
