Development of novel analytical methods to trace small micro- and nanoplastics in food matrices

a diameter smaller 1 µm, called nanoplastics (NP s) that could be found in food matrices and environmental samples, by means of specific measurement techniques. Therefore, the aim of this work is to develop ...

Validation of an animal-free analytical method for the detection of bacterial endotoxins in human vaccines

assays are suitable for all vaccines tested, although the most appropriate technique of endotoxins quantification depends on the type of vaccine. Health Topics:  Effectiveness and safety of vaccines, ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...

Spectroscopic approaches for conformity analysis of e-liquids

modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...

From b to y ions, a decade of experience with peptide and protein analysis

recombinant expression technologies, and peptide synthesis have led to an increased development of protein and peptide therapeutics. Due to improved and simplified manufacturing techniques, disregard for patent ...

Analysis of mineral oil in food: An analytical challenge

volatility. Since these two fractions have a different toxicological relevance, it is important to quantify them separately. Commonly, an online technique existing of a combination of Liquid Chromatography with ...

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 ...

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 ...
