Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium

a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC- DAD) was also successfully validated. Next, real-life illegal antimicrobial samples ...

Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium

in vitro dissolution studies on SF antimicrobials to estimate the in vivo bioavailability and bioequivalence. Real-life illegal antimicrobial samples, confiscated by inspectors from the Belgium Federal ...

Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium

decreased over time. Before the revised TPD came into force, almost half of the samples was not conform in contrast to less than 15% non-conformities observed in the period 2017-2018. Moreover, also the ...

Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids

issue, a proper sample preparation is needed, to improve the life span of the column and reduce the total number of cuts in the GC-column. The aim of our study is to quantify potential harmful flavourings ...

Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy

Physicochemical Characterisation of the E171 Food Additive

CEN / TC 352 guidelines. The E171 samples were purchased on the Belgian market or were obtained from European producers. To measure the minimal external dimension of the constituent particles of E171, ...

Batch release of vaccines in Europe: from method transfer to first commercial batch available on the market. Straightforward approach that requires a proactive mindset of the manufacturer.

structural differences of equipment (between manufacturer and OMCL), shipment of samples and reagents,…. Assay variability and possible changes in analytical methods and specifications during the registration ...

RNA-based drug susceptibility testing of Mycobacterium tuberculosis

format. In short, 200 µl of a positively flagged MGIT culture is spiked with a specific concentration of a drug, while a control sample is incubated in absence of the drug. Multiplex mRNA quantification is ...

Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?

samples of E174 and ten food items containing E174 were investigated for their number-based size distribution of Ag particles. The food items were as well investigated for their total Ag content. Single ...

Arsenic Speciation Analysis Elucidates the Risk Assesment of Food Supplements with Ingredients of Marine Origin. 9th Nordic Conference on plasma spectrochemistry

the consumption of these types of FS, based on 60 samples collected in a Belgian market study. In this context, the determination of the most toxic fraction, inorganic arsenic (As i) and the non-toxic ...
