Development of a monoclonal antibody sandwich ELISA for the determination of antigen content and quality in diphtheria vaccines.
different human vaccine products. We demonstrate the ability of the assay to discriminate between batches of different content and quality using vaccine batches that were prepared to contain differing amounts ...
Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX
products and domestic cooking to enhance the appearance of food. To obtain specific hues, inorganic food additives containing (nano)particles are mixed in varying concentrations, and pearlescent pigments ...
Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
particular, samples containing NP s have been separated by hydrodynamic diameter with AF4, then analyzed by MADLS to characterize their size and size distribution. Finally, the polymer type of the NP s has been ...
Development, validation, and application of a multimatrix UHPLC-MS/MS method for quantification of Datura-type alkaloids in food
commercial foods. Only 26% of the analysed food samples contained one or both TA s. The mean concentrations for atropine and scopolamine amounted to 21.9 and 6.5 µg kg, respectively, while the maximum ...
Applicability of the DPRA on mixture testing: challenges and opportunities.
containing either two known skin sensitizers with varying potencies, or a combination of a skin sensitizer with a non-skin sensitizer, or multiple non-sensitizers. Experiments A and B revealed that one ...
Release of silver and titanium from face masks traded for the general population.
varying from 0.03 up to 36 % of total Ag content, in four out of the eight face masks that claimed antimicrobial properties and that contained Ag. The leaching data of titanium (Ti) showed that despite TiO ...
Towards Less Plastic in Food Contact Materials: An In-Depth Overview of the Belgian Market.
environmentally friendly and websites describing homemade FCM s. The first screening identified 10,523 articles. The following data cleaning process resulted in a homogeneous dataset containing 2688 unique entries, ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
alleged therapeutic benefits, a low potential for abuse and lack of the typical psychoactive effects associated with the use of cannabis products containing high levels of ∆9-tetrahydrocannabinol (∆9- THC). ...
Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
analyzed, whereof nine samples contained MC s. Moreover, three samples exceeded the concentration of 1 µg g−1 total microcystins, previously proposed as a guideline value. Microcystis sp. were determined as ...
Spectroscopic approaches for conformity analysis of e-liquids
public health. E-liquids typically contain four main ingredients: propylene glycol, glycerin, flavorings and nicotine. The latter is of course not present in zero liquids. The primary issue is the content of ...
