Microbial quality analysis of falsified medicines seized by controling agencies

refers to the amount and type of microorganisms present in a sample and reflects the level of biological contamination and associated potential health risks upon consumption of the product. We initially ...

THE ANALYSIS OF ILLICIT DRUGS COLLECTED DURING A SUMMER FESTIVAL AND EVALUATION OF THE NARCOREADER FOR ON-SITE ANALYSIS OF MDMA

time-consuming and of high cost. There is a need for more rapid and still accurate analysis, with cost-effective and portable methods. Aim: As the first goal of this study, a selection of drug samples is analysed ...

Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans

environmental samples. This has a negative downstream effect on possible risk assessment studies that would establish the exposure and influence of the different cyanotoxins on public health, and on the final ...

Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

based on the sequencing of all genetic material of the sample without isolation has become available some years ago, e.g. shotgun metagenomics. It allows to get a screenshot of every microbiological ...

CHROMATOGRAPHIC FINGERPRINT DEVELOPMENT FOR THE DETECTION OF TRIBULUS TERRESTRIS IN PLANT FOOD SUPPLEMENTS

by preparing triturations of TT with herbal matrices in varying ratios (½, ⅕, 1/10, 1/15, ½0). Twenty unknown samples were screened for TT and further confirmation was carried out by UH ¨ PLC-mass ...

Development of a data-intensive centralized system for surveillance and outbreak investigation of bacterial pathogens using whole-genome sequencing

surveillance. User-friendly access to the workflows is provided to both internal and external scientists through web-accessible Galaxy instances. In emergencies, the sample-to-result time for WGS can be ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

screening of e-liquid samples to check their compliance to the TPD i.e. non-nicotine labeled e-liquids should not contain nicotine and the maximum nicotine concentration of nicotine-labeled e-liquids should ...

Chemical and toxciological characterization of e-liquid cigarettes

the revised TPD. The samples were examined for the presence of nicotine, nicotine-related impurities, volatile organic compounds, caffeine, taurine and the harmful flavours diacetyl and acetylpropionyl. ...

Characterization of Nanoparticles: Measurement Processes for Nanoparticles: Characterization of nanomaterials by transmission electron microscopy: Measurement procedures

Processes for Nanoparticles surveys this fast growing field, including established methods for the physical and chemical characterization of nanoparticles. The book focuses on sample preparation issues ...

Bepaling van spoorelementen in diverse matrices met spectrometische technieken.

preparations were mineralized with HNO3 in microwave oven and the concentrations of As, Cd, Ni, Pb in the samples were analyzed with an ICP- MS. Hg in these samples was determined with the AMA. 2.textile samples ...
