Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry

for ∑ MCCP s in all food matrices analysed. The selection of the internal standard was a significant factor in the accuracy of the method and highlights the strong need for more appropriate isotopically ...

Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry

(< 0.9 μgkg−1). The quantification per-formed by isotopic dilution allowed the complete correction of matrix effect and led to very good validation data with a meanrecovery close to 100% and ...

Childhood leukaemia near nuclear sites in Belgium, 2002–2008

power plants of Doel or Tihange nor around the nuclear site of Fleurus, which is a major manufacturer of radioactive isotopes in Europe. Around the site of Mol-Dessel, however, two- to three-fold ...

Determination of total Ti in candy

ions was high enough to predict a worst-case scenario. Based on the isotopic abundance of the different masses, the results of this interference test, preliminary tests and literature data, measurements ...

Childhood leukaemia near nuclear sites in Belgium, 2002-2008.

of acute leukaemia was observed around the nuclear power plants of Doel or Tihange nor around the nuclear site of Fleurus, which is a major manufacturer of radioactive isotopes in Europe. Around the ...

Analysis of glyphosate residue in liver by UPLC-MS/MS

/1257½013 criteria. The quantification is performed by isotopic dilution leading to very good validation data with a mean recovery close to 100% and a RSD below 10%. Service:  Éléments traces et nanomatériaux ...

Thyroid cancer incidence in the vicinity of nuclear sites in Belgium 2000-2008

Analysis of chlormequat residue in milk by UPLC-MS/MS

very good validation data are correlated to the robustness of the method and to the use of an isotopic surrogate. Service:  Éléments traces et nanomatériaux Spoorelementen en nanomaterialen Trace ...

A proteomics approach for the quantification of Staphylococcus aureus enterotoxins a and b in several matrices using uplc-msms analysis.

developed and are validating method to specifically quantify SE s in pork meat using stable isotope dilution and UPLC – MSMS analysis. Pork meat was spiked with SEA and/or SEB. Next we extract the SE s from ...
