Spectroscopic approaches for conformity analysis of e-liquids
Therefore, it is necessary to monitor the compositions of the products on the market and conduct surveillance studies. In Belgium this is performed under the coordination of the Federal Public Service of ...
Importance of anti-SARS-CoV-2 assay antigenic composition as revealed by the results of the Belgian external quality assessment (EQA) scheme.
necessity of external quality assessment schedules and importance of antigenic composition of serologic SARS-CoV-2 assays. Health Topics: Effectiveness and safety of vaccines, medicines and health products- ...
Chemical and toxciological characterization of e-liquid cigarettes
PhD thesis was therefore to first determine the chemical composition of the liquids used in e-cigarettes (e-liquid) and next to investigate toxicological aspects of flavouring substances present in ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...
Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
prothrombotic FXI a was assessed with confident identification of a 1ng/mg spike. Moreover, different residuals compositions were profiled for various commercial Ig products. Using a quantitative label free ...
Impurity fingerprints for the identification of counterfeit medicines--a feasibility study.
medicines are manufactured in non good manufacturing practices (GMP) conditions by uncontrolled or street laboratories. Their chemical composition and purity of raw materials may, therefore, change in the ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
concerns about their long-term health effects, including potential lung damage. Therefore, it is essential to closely monitor and study the composition of e-liquids. E-liquids typically consist of propylene ...
