Development, validation and application of multi-class methods for the analysis of food additives by liquid chromatography coupled to tandem mass spectrometry
quantification, accuracy, repeatability, and intra-laboratory reproducibility. Finally, the methods were successfully applied to eighty-four actual samples. All additives were found below authorised levels. ...
A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market
showed good sensitivity, accuracy, and precision. It has been applied to 49 samples from the Belgian market. In 26 samples, not a single ergot alkaloid was detected while in 23 out of 49 samples at least ...
Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
Reference Laboratory (EURL) interlaboratory study on CP s in food. The EURL ’s accuracy criteria was met for both homologue groups in all food matrices with overall accuracy in the range of 76–130% for ...
A genoserotyping system for a fast and objective identification of Salmonella serotypes commonly isolated from poultry and pork food sectors in Belgium.
assay were validated with a 100% accuracy, using 553 Salmonella and non-Salmonella strains in total. Health Topics: Food consumption and food safety Consommation et sécurité alimentaires ...
Development of a genoserotyping system for the identification of Salmonella serotypes
reaching an accuracy above 99%. Finally, the complete genoserotyping system was evaluated for its ability to completely identify auto-agglutinable isolates which cannot be typed by the ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
methods using spiked samples at three concentration levels (0.5-5 and 25 ng g−1). The parameters accuracy and precision fulfill the criteria. Calibration curves are linear between 0.5 and 50 ng −1. The ...
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, ...
Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
on bioanalytical method validation using Certified Reference samples from the German External Quality Assessment Scheme (G-Equas) proficiency test. All obtained results for accuracy and recovery are ...
On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
method (10min) was assessed for three concentration levels and were found to be less than 8% for each analyte while the accuracy was between 89 and 113%. To further improve the sensitivity of this approach ...
An Alternative Method Validation Strategy for the European Decision 2002/657/EC
these methods are defined in the European Decision 2002/657/ EC. (1) A performance characteristic is a quality measure of the analytical method. The performance characteristics specificity, accuracy ...
