Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
matrices with spectrometric techniques. With the aim of detecting possible risks for public health and to be able to give advice to the authorities (including EFSA, the FASFC,…) in the context of the ...
Development of a genoserotyping system for the identification of Salmonella serotypes
adapted to the need of the field, especially for the professionals of the food sector who need to rapidly, accurately and cost-efficiently detect the serotypes targeted by the legislation. Fortunately, ...
All in one method for the analysis of multiclass food additives using UHPLC-MS/MS
results will show the recoveries obtained for each group of FA s associated with the limit of detection for the non-authorized compounds and the limit of quantification for the FA s. Feasibility of this ...
Determinants of persistent organic pollutant (POP) concentrations in human breast milk of a cross-sectional sample of primiparous mothers in Belgium
HCH) and two brominated flame retardant congeners (BDE-47, BDE-153) were detected at concentrations above the limit of quantification in >50% of the breast milk samples. Maternal age and BMI were ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
about 35% of the samples contained known and/or unknown impurities beyond the Ph. Eur. limits [3]. Concerning the dissolution tests, 47% of samples were not compliant as the amount of drug released is ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
detection limit for FeOx of about 32-47 nm. The distribution of hydrodynamic diameters of goethite particles detected with FlFFF, NTA and DLS were similar but the values were twice as large as the Fe cores of ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
study included an assessment of the limit of detection, working range, selectivity, precision, trueness, robustness, and ruggedness. An uncertainty that was associated to intermediate precision in the ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
detection in the range of 0.03–0.21 μg kg−1, and limit of quantification in the range of 0.09–0.48 μg kg−1), and precision (relative standard deviation (RSD) ≤ 12.9%), the analytical method was successfully ...
Detection and discrimination of five E. coli pathotypes using a combinatory SYBR® Green qPCR screening system
silico and in situ selectivity, sensitivity, repeatability, and reproducibility evaluation of the 13 SYBR ® Green qPCR assays. Each target displayed a selectivity of 100%. The limit of detection of the 13 ...
