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. ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
sugar-coated confectionery and pristine food-grade titanium dioxide was developed. Special emphasis was placed on the sample preparation procedure, crucial to reproducibly disperse the particles before analysis. ...
Assessment of an application on a detoxification process of groundnut press cake for aflatoxins by ammoniation
that the process is reproducible and reliable and to demonstrate that the detoxification is not reversible. In addition, genotoxicity testing of extracts of the treated feedingstuff and of the identified ...
Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
the method complied with the acceptable range of 70–120% for most CG s, and relative standard deviations were at maximum 14% and 19% for repeatability and reproducibility, respectively. Method linearity ...
Generation and Characterization of Six Recombinant Botulinum Neurotoxins as Reference Material to Serve in an International Proficiency Test.
hardly be compared. In this study, the six BoNT/ A1- F1 prototypes were successfully produced by recombinant techniques, facilitating handling, as well as improving purity, yield, reproducibility and ...
A multiplex oligonucleotide ligation-PCR as a complementary tool for subtyping of Salmonella Typhimurium
markers was confirmed in a serial passage experiment. The validation of the MOL- PCR assay for subtyping of S. Typhimurium and S. 1,4,[5],12:i:- on 519 isolates shows that the method is rapid, reproducible ...
Development and performance assessment of a qualitative SYBR® green real-time PCR assay for the detection of Aspergillus versicolor in indoor air.
Reproducibility of Results Sensitivity and Specificity Staining and Labeling Abstract: Currently, contamination of indoor environment by fungi and molds is considered as a public health problem. The monitoring of ...
Determination of selected veterinary antimicrobials in poultry excreta by UHPLC-MS/MS, for application in Salmonella control programs.
filtration prior to analysis. The method was validated according to Commission Decision 2002/657/ EC for linearity, apparent recovery/trueness, repeatability, reproducibility, limit of quantification, limit of ...
Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
Linear Models Renal Insufficiency, Chronic Reproducibility of Results Tandem Mass Spectrometry Abstract: Despite decades of creatinine measurement in biological fluids using a large variety of analytical ...
New trait-specific qualitative SYBR®Green qPCR methods to expand the panel of GMO screening methods used in the CoSYPS
Method acceptance parameters such as the sensitivity, specificity and repeatability were assessed as well as the robustness of the methods. Additionally, the reproducibility was evaluated by transferring ...
