A Summer of Cyanobacterial Blooms in Belgian Waterbodies: Microcystin Quantification and Molecular Characterizations
sequencing. The cyanobacterial diversity for two water samples was characterized with amplicon sequencing. Microcystins were detected above limit of quantification (LOQ) in 68 water samples, and the World ...
Strategy and Performance Evaluation of Low-Frequency Variant Calling for SARS-CoV-2 Using Targeted Deep Illumina Sequencing
The performance of detection and quantification of low-frequency variants using whole genome sequencing (WGS) of SARS-CoV-2 remains largely unknown. Here, we evaluated the detection and quantification ...
The purity of tattoo inks, screening substances of high concern
quantification method was validated to quantify 5-nitro toluidine and 4-chloroaniline in tattoo inks with high accuracy. The method was validated according to the total error approach with an acceptance value of ...
In Vivo Kinetics and Biotransformation of Aflatoxin B1 in Dairy Cows Based on the Establishment of a Reliable UHPLC-MS/MS MethodDataSheet1.docx
successfully validated by the determination of linearity (R2 ≥ 0.990), sensitivity (lower limit of quantification, 0.1–0.2 ng ml−1), recovery (79.5–111.2%), and precision relative standard deviation (RSD) ...
A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market
UHPLC- MS / MS method was developed. It is suitable for the quantification of six ergot alkaloids: Ergocornine, ergocristine, ergometrine, ergosine, ergotamine, α-ergocryptine, and their corresponding ...
Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
be respected (< 20mg/ml). The main objective of this paper is to develop a handheld NIR, Raman or SERS spectroscopic method combined with chemometrics (PLS and PCA) for detection and quantification ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
of ICH guidelines for the quantification of four flavourings with a potential health concern for e-cigarette users. Health Topics: E-cigarette E-cigarette E-sigaret Service: Médicaments et produits ...
Development of a multiplex mass spectrometry method for simultaneous quantification of urinary proteins related to respiratory health

CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
method for the routine analysis of CBD oil samples. Eighteen CBD samples were selected on the Belgium market for analysis. This method allows the quantification of CBD, the legality check for the Δ9- THC ...
Evaluation of the shucking of certain species of scallops contaminated with domoic acid with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation
concentration levels was above the limit of quantification (LOQ) and only these data were used for the assessment. Shucking in most cases resulted in a strong decrease in the toxin levels. Statistical analysis of ...
