Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products
for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP- MS) is thereby a promising technique as it is capable of sizing and ...
A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
techniques in order to obtain classification models. A first classification model is calculated based on the infrared data and gives a first idea about the plant suspected to be present. This suspicion is then ...
Dual DNA Barcoding for the Molecular Identification of the Agents of Invasive Fungal Infections.
culture-dependent methods toward molecular techniques, including DNA barcoding, a highly efficient and widely used diagnostic technique. Fungal DNA barcoding previously relied on a single barcoding region, the ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
users safety, analytical characterization of the refill liquids (e-liquids) used for e-cigarettes is essential. Different techniques have been used for the qualitative and quantitative chemical ...
Combining TEM with single particle ICP-MS: assessing the size of individual nanoparticles in food additives by multiple techniques
Publication Type: Scientific poster, presentation or proceeding Authors: Nadia Waegeneers; Delfosse,L.; Sandra De Vos; Eveline Verleysen; Jan Mast Source: Workshop: Physicochemical characterisation of nano-sized particles in food, Sciensano, Issue Sciensa ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
limitations of existing analytical techniques, and the lack of validated studies and reference materials. This book chapter summarizes these challenges and, in addition, suggests a screening strategy for ...
The development of a characterisation approach for Amphetamine, Cocaine and Ketamine samples, using infrared and Raman techniques
Publication Type: Dissertation Authors: Andries Raes; Tamara Vanhaecke; Eric Deconinck Source: VUB, Jette, p.58 (2019) Health Topics: Médicaments illégaux Illegal medicines Illegale geneesmiddelen Service: Médicaments et produits de santé Geneesmiddelen ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
a slightly different outcome between the newly developed UV-detection method and the targeted MS approach was found, due to the sensitivity of the different detection techniques. However, in the context of ...
Identification of fungal isolates by MALDI-TOF mass spectrometry in veterinary practice: validation of a web application.
species was isolated from various animals (including pets, cattle, and zoo animals) and identified using both MALDI- TOF MS and conventional techniques. The performance of the 2 methods was compared, and ...
Contribution of chronic conditions to gender disparities in health expectancies in Belgium, 2001, 2004 and 2008
was applied to life tables to estimate DFLE and LED using the Sullivan method. Decomposition techniques were used to assess the contribution of mortality and disability and further of causes of death ...
