Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products
samples were prepared for analysis according to a slightly modified version of the method of Jensen et al. [2]. The E174 food additives showed a large silver background concentration combined with ...
Physicochemical characterisation of several types of the E171 food additive
https://www.sciensano.be/fr/biblio/physicochemical-characterisation-several-types-e171-food-additive
particle inductively coupled plasma mass spectroscopy (sp- ICP- MS) following CEN / TC 352 guidelines. The E171 samples were purchased on the Belgian market or were obtained from European producers. In ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
However, no validations have yet been performed with food additives or real samples containing food additives requiring a sample preparation step prior to analysis. A single-particle inductively coupled ...
Prevalence of Anaplasma phagocytophilum in humans in Belgium for the period 2013-2016
whose samples were analyzed by the NRC for Anaplasma in a four-year period (2013-2016). Health Topics: Anaplasmose Anaplasmosis Anaplasmose Health and disease monitoring Surveillance de la santé et des ...
Determination of endocrine disrupting compounds in human placenta by UPLCESI-MS/MS
quantified in human placenta samples The major compounds found were parabens and bisphenols Highest concentration levels for methyl- and propylparaben and highest quantification frequency for octylphenol ...
Levels of Persistent organic pollutants in breast milk: Belgian results from the 6 th WHO-coordinated survey
POP s in breast milk POP s levels in Belgian breast milk samples still decrease over time Main POP s still measurable are DDT, HCB and B- HCH breast milk advised as first choice for nursing babies The ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using ...
A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
The approach was applied in a small market study comprising 35 dietary supplements for slimming and 34 for male potency enhancement. In total 21 samples were found to contain one of the five ...
Validation of a Bioinformatics Workflow for Routine Analysis of Whole-Genome Sequencing Data and Related Challenges for Pathogen Typing in a European National Reference Center: as a Proof-of-Concept.
employed typing schemas (including, among others, core genome multilocus sequence typing), and serogroup determination. We analyzed a core validation dataset of 67 well-characterized samples typed by means ...
Bigger and Better? Representativeness of the Influenza A Surveillance Using One Consolidated Clinical Microbiology Laboratory Data Set as Compared to the Belgian Sentinel Network of Laboratories.
subject to local regional variations. A subset of the Influenza samples had their whole genome sequenced so that the observed epidemiological trends could be correlated to molecular observations from the ...
