Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products
for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP- MS) is thereby a promising technique as it is capable of sizing and ...
Real-time prediction of influenza outbreaks in Belgium.
dynamics of other influenza seasons. In order to validate the proposed approach, we used data collected by the Belgian SGP s for the influenza seasons 2010-2016. In spite of the great variability among ...
In vitro antigenotoxic activity, in silico ADME prediction and protective effects against aflatoxin B1 induced hepatotoxicity in rats of an Erythrina latissima stem bark extract
stem bark extracts (ELBE) may counteract the in vivo hepatotoxic effects of aflatoxins, contaminants in food and feed. An HPLC- DAD method was developed and validated to determine the level of flavonoid ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory context. ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
approach on the certified reference materials ERM- FD100 and ERM- FD304. The image analysis method was validated in an inter-laboratory study by 19 laboratories, which resulted in a within-laboratory ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
negative electrospray ionization. Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...
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 methods are “fit-for-purpose” and provide high-quality results. A harmonized framework with guidelines for the validation of WGS workflows does currently, however, not exist yet, despite several ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
