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

data were needed. Therefore, a consumption survey for algal-based food supplements was launched, showing that 13.00 % of the 554 respondents used these products. The majority of the users consumed these ...

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

improvement of Raman PLS model and further SERS studies with tests on a larger number of samples are still needed. Health Topics:  E-sigaret E-cigarette E-cigarette Service:  Médicaments et produits de santé ...

Chemical and toxciological characterization of e-liquid cigarettes

analytical methods used in these studies have not always been well validated and thus the results of these studies need to be critically examined; three main problems could be uncovered: (1) the content of ...

Development of a genoserotyping system for the identification of Salmonella serotypes

adapted to the need of the field, especially for the professionals of the food sector who need to rapidly, accurately and cost-efficiently detect the serotypes targeted by the legislation. Fortunately, ...

DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS

GC- FID- MS method. The run time for lubricants and AHP s were respectively, 28 and 27 min. The matrix-effect of tampons was evaluated and confirmed, resulting in the need for optimization. The method ...

Innate signaling by mycolate esters of the cell wall of Mycobacterium tuberculosis and relevance for development of adjuvants for subunit vaccines

control and eliminate TB, a better vaccine, efficient drug treatments and more rapid and cheaper diagnostic techniques are needed.  In this PhD thesis we have attempted to provide additional information to ...

Development of molecular tools for rapid detection and quantification of indoor airborne molds to assess their impact on public health

demonstrated that SYBR ®green qPCR assays can be used as a molecular alternative for monitoring of contaminated samples while eliminating the need for culturing and thereby considerably decreasing the required ...

Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach

tablets in an intact blister. A perfect discrimination between genuine and counterfeit medicines can be obtained by SIMCA and PLS- DA without the need to remove the tablets from the blister, thereby keeping ...
