Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
impingers, many studies failed to validate critical steps such as aerosol recovery, blank corrections, and the extent of matrix effects. In addition, poor inorganic methodological practices were often applied, ...
Method development for analysis of nanoplastics in drinking water and milk using transmission electron microscopy (TEM)
preparation procedure, was significantly improved from ~10¹⁰ to ~10⁸ particles/mL by implementing a two-step centrifugation protocol. For milk, advanced matrix digestion methods are crucial for recovering ...
Simultaneous quantification of Ibuprofen and Paracetamol in combined tablet formulations by UV–VIS spectrophotometry and chemometric modelling
analyses, if an absence of signal interference between the component of interest and other matrix constituents is assured. However, chemometric modelling broadens the applicability of UV – VIS ...
Whole-genome sequencing of soil- and foodborne Bacillus cereus sensu lato indicates no clear association between their virulence repertoire, genomic diversity and food matrix
Publication Type: Peer reviewed scientific article Authors: Bram Jacobs; Bogaerts, Bert; Verhaegen, Marie; Vanneste, Kevin; De Keersmaecker, Sigrid C.J.; Roosens, Nancy H.C.; Rajkovic, Andreja; Mahillon, Jacques; Tom Van Nieuwenhuysen; Koenraad Van Hoorde ...
An interlaboratory proficiency test using metagenomic sequencing as a diagnostic tool for the detection of RNA viruses in swine fecal material.
types. The suitability of experimental design to a given pathogen/sample matrix combination, quality assurance, interpretation, and follow-up investigation remain critical factors for the diagnostic ...
Advances in monitoring-centered quantification of microcystins in fish matrix using UHPLC-MS/MS
a plethora of different fish species. While reporting quantified cyanotoxins in multiple fish species, most studies do not take into account the potential differences of matrix for quantification in fish ...
10 years of organizing L. monocytogenes enumeration proficiency testing in food matrices at the Belgian national reference laboratory.
reliability of the participant’s results. The NRL organizes L. monocytogenes enumeration PT once a year, using one food matrix. The methods used by the participants must belong to a list of methods approved by ...
Antimicrobial resistance in ESBL and indicator E. coli, Campylobacter spp.,Salmonella spp., methicillin-resistant Staphylococcus aureus (MRSA) and Enterococcus faecalis and faecium isolated from food and food-producing animals (primary production) in 2023
Typhimurium (26%) and Derby (20%). Resistances to all antimicrobials but trimethoprim and amikacin, which is detected for the first time in this matrix, decreased in 2023. In the 3 Salmonella spp. isolates ...
Unlocking the genomic landscape: Results of the Beyond 1 Million Genomes (B1MG) pilot in Belgium towards Genomic Data Infrastructure (GDI)
matrix, called Maturity Level Model (MLM), that contained 49 indicators across eight domains: I. Governance and strategy; II. Investment and economic model; III. Ethics, legislation and policy; IV. Public ...
Dietary exposure of Sorbates (E 200 – 202) and Benzoates (E 210 – 213) for the Belgian population
these FA s was estimated. Three matrix-matched analytical methods were developed using ion chromatography coupled with conductivity detection. The methods were validated in-house and applied to 387 ...
