Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
× time points) were used for selection of orthogonal wavelengths by conducting a correlation analysis. After preparation of triturations, recording of the fingerprints and creation of datasets (corrected ...
Surveillance van COVID-19 gerelateerde mortaliteit in België, epidemiologie en methodologie tijdens 1e en 2e golf (maart 2020- 14 februari 2021)
in België. Deze oversterfte was een belangrijke indicator in de COVID-19- epidemie om te valideren dat de epidemiologische rapportage van COVID-19-gerelateerde sterfte correct gebeurde tijdens ...
Surveillance de la mortalité COVID-19 en Belgique, épidémiologie et méthodologie durant la 1re et 2e vague (mars 2020- 14 février 2021)

Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium
parameters of drug quality control [2]. In this context, SF antimicrobials containing the correct dosage of claimed API s can exhibit poor dissolution performance. Thus, it is necessary and crucial to execute ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
(< 0.9 μgkg−1). The quantification per-formed by isotopic dilution allowed the complete correction of matrix effect and led to very good validation data with a meanrecovery close to 100% and ...
DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS
FID- MS was used to determine fragrances in lubricants using standard addition to correct for matrix effects. The established HS- GC- FID- MS method was optimized and validated. The observed ...
MALDI-TOF for the identification of Mycobacteria and their drug resistance profiles
MALDI- TOF MS and outcomes vary from 55% correct identifications to 97%2-4. In this study, we optimized an extraction protocol and evaluated its efficiency using the Brüker Biotyper system v3.0 for 194 ...
MALDI-TOF mass spectrometry identification of filamentous fungi in the clinical laboratory2175
501 (80%) and 556 (89%) were correctly identified by conventional methods and MS respectively. Compared with the conventional method, MS dramatically enhanced the performance of the identification of ...
Association between variables used in the field substitution and post-stratification adjustment in the Belgian health interview survey and non-response.
non-response, the impact of field substitution on the survey results may be minimal, either because there was no bias of relevance or it was not captured. The usefulness of field substitution to correct for ...
