Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
more standardization methodologies were introduced in the analysis of metal(loid)s from aerosols, a huge divergence in sample preparation can be found in the literature. This work aimed to provide an ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
chromatography-mass spectrometry (GC- MS), liquid chromatography-mass spectrometry (LC- MS), and others, although effective, suffer from drawbacks, including complex sample preparation, high costs, lengthy analysis ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
embedded within the fibres, while in the other three cases it is at least partly present on the surface of fibres. The amount of silver-containting particles detected in each sample is too low to build ...
Pyrogen testing of phage therapeutic products
Queen Astrid Military Hospital in Brussels. With a few exceptions, the results on different phages demonstrate that in general pyrogenic contamination is low for most samples. Health Topics: ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
using the ‘total error’ approach, applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 ...
COVID-19 vaccine effectiveness against symptomatic infection and hospitalisation in Belgium, July 2021 to May 2022.
sampling.ResultsWe included 1,932,546 symptomatic individuals, of whom 734,115 tested positive. VE i against Delta waned from an initial estimate of 80% (95% confidence interval (CI): 80-81) to 55% (95% CI: 54-55) ...
Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 CBD-liquids investigated in this ...
The GEONs API-fingerprint program: Tackling falsifications of APIs
since the quality and quantity of the API might be within the current standards. Instead, methods that allow distinction of API samples, according to their source are needed. Within the General European ...
Importance of anti-SARS-CoV-2 assay antigenic composition as revealed by the results of the Belgian external quality assessment (EQA) scheme.
Immunoglobulin A Immunoglobulin G Immunoglobulin M Male Phosphoproteins SARS-CoV-2 Sensitivity and Specificity Spike Glycoprotein, Coronavirus Abstract: We report on sample IS /17575 since it generated highly ...
