Study of the possible migration risks of food contact materials for children under 3 years

Monitoring and quantification of these compounds was done using GC- and LC-QqQ- MS methods, for which several validation parameters were determined (sensitivity, selectivity, linearity, accuracy, precision, ...

Detection of pyrrolizidine alkaloids in milk and honey on the Belgian market using UHPLC-MS/MS.

PA s at (very) low levels.Analytical methods based on UPLC separation and MS / MS detection were developed for the analysis of 16 PA s and 13 PANO s in honey and milk matrices at WIV- ISP. The sample ...

Occurrence of polybrominated diphenyl ethers and emerging halogenated flame retardants in food items

dechlorane plus (syn- DP and anti- DP) in various food items was assessed using an analytical method developed and validated in the frame of the this Project. This novel method uses low sample amounts and ...

Brominated flame retardants in Belgian foodstuffs- recent evaluation by a novel UPLC-MS/MS method

pigments and eventually other matrix components from the extract. The method is applicable to a wide variety of food matrices and was in-house validated. Representative portions of food samples belonging to ...

Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.

toxicity assessment, the most toxic migrating compounds were selected to be monitored and quantified using validated GC- and LC-QqQ- MS methods. The effect of several ‘real-life-use conditions’, such as ...
