Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?
concentration. The number-based size distribution of Ag particles was verified by transmission electron microscopy. Sample preparation, which included separation of the particles from the matrix in case of food ...
Convenient one-pot formation of highly functionalized 5-bromo-2-aminothiazoles, potential endocannabinoid hydrolase MAGL inhibitors
Abstract: Highly functionalized 5-bromo-2-amino-1,3-thiazoles bearing various substituents could be easily prepared by a rapid and efficient one-pot method, using simple starting materials and mild conditions ...
Analytical strategies for the determination of pyrrolizidine alkaloids in plant based food and examination of the transfer rate during the infusion process
Pyrrolizidine alkaloids salads Tea transfer rate Abstract: Two sample preparation methods were developed (graphitised carbon and C18 solid phase extraction clean-up) and validated in house using liquid ...
Impurity profiling of the most frequently encountered falsified polypeptide drugs on the Belgian market
these falsified preparations are produced outside the legally required quality systems, end-users have no guarantee regarding the efficacy and safety of these products. Although falsified samples of ...
Reproductive Disorders and Leptospirosis: A Case Study in a Mixed-Species Farm (Cattle and Swine).
species, the direct link between the two animal units was not found. Factors such as drinking from the same water source and the use of manure prepared with the swine slurry might raise suspicion of ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
in terms of resolution and symmetry factor for the targeted peptide set. Hence, the operational conditions were further optimised for the identification of illegal preparations via mass spectrometry ...
Development and validation of a quantitative UHPLC-MS/MS method for selected brominated flame retardants in food.
tetrabromobisphenol A (TBBPA), hexabromocyclododecanes (HBCD s), tetrabromobisphenol S (TBBPS) and bromophenols (BP s), in various food matrices. The sample preparation consisted of extraction of TBBPS with acidified ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
identification of a specific toxic or regulated plant in herbal preparations or plant food supplements is a real challenge, since they are often powdered, mixed with other herbal or synthetic powders and ...
The use of Stationary Phase Optimized Selectivity Liquid Chromatography for the development of herbal fingerprints to detect targeted plants in plant food supplements.
