Development, validation and application of multi-class methods for the analysis of food additives by liquid chromatography coupled to tandem mass spectrometry
quantification, accuracy, repeatability, and intra-laboratory reproducibility. Finally, the methods were successfully applied to eighty-four actual samples. All additives were found below authorised levels. ...
Multicentre study on the reproducibility of MALDI-TOF MS for nontuberculous mycobacteria identification.
extraction procedures. Few multicentre studies on the reproducibility of MALDI- TOF have been performed so far, none on mycobacteria. The aim of this study was to evaluate the reproducibility of MALDI- TOF for ...
Intra- and inter-laboratory comparison of mDixon and FastFung broths for Malassezia antifungal susceptibility testing.
literature. FFB showed to enhance Malassezia growth and displayed 100% (±2-fold dilution) EA s demonstrating similar performances to mDIXB. In addition, the MIC data obtained by using the FFB were reproducible ...
4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea
allowing us to include most older historical data that have been obtained during the nineteen seventies and eighties. Our approach included reproducible and quality controlled procedures from data collection ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
sugar-coated confectionery and pristine food-grade titanium dioxide was developed. Special emphasis was placed on the sample preparation procedure, crucial to reproducibly disperse the particles before analysis. ...
Assessment of an application on a detoxification process of groundnut press cake for aflatoxins by ammoniation
that the process is reproducible and reliable and to demonstrate that the detoxification is not reversible. In addition, genotoxicity testing of extracts of the treated feedingstuff and of the identified ...
Validation strategy of a bioinformatics whole genome sequencing workflow for Shiga toxin-producing Escherichia coli using a reference collection extensively characterized with conventional methods
a validation strategy specifically adopted to WGS, we demonstrated high performance with repeatability, reproducibility, accuracy, precision, sensitivity and specificity above 95 % for the majority of all ...
Morbidity Statistics: 2019 Pilot Data Collection Belgium, Final Report
were initiated while paving the way for enhanced future data exchanges and collaborations within other projects. Methodologies and tools were developed to increase the reproducibility of the analyses and ...
Biological effects of radiofrequency fields: Testing a paradigm shift in dosimetry
Specific absorption rate Abstract: Biological effects have been reproducibly reported in rodents exposed to radiofrequency fields (RF) without significant change of the body temperature. These observations ...
Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
the method complied with the acceptable range of 70–120% for most CG s, and relative standard deviations were at maximum 14% and 19% for repeatability and reproducibility, respectively. Method linearity ...
