J Chromatogr A 1088:40-8. 2005..The method was validated for the simultaneous qualitative and quantitative determination of the eleven FQs in pig kidney around their maximum residue limit (MRL) as defined in the European Council Regulation 2377/90/EEC...
Identification, characterization and determination of metal-binding proteins by liquid chromatography. A reviewM B de la Calle Guntiñas
European Commission, Joint Research Centre, Institute for Reference Materials and Measurements IRMM, Retieseweg, 2440, Geel, Belgium
Anal Bioanal Chem 374:369-78. 2002..In this review, special attention is paid to studies dealing with the glycosylation of transferrin, and with the glycated isoform of haemoglobin...
Validation of a liquid chromatography-tandem mass spectrometry method for the simultaneous quantification of 11 (fluoro)quinolone antibiotics in swine kidneyB Toussaint
J Chromatogr A 976:195-206. 2002..Limits of quantification < or = 50 microg/kg could be obtained in swine kidney, much lower than every MRL. The validation is discussed. This work was carried out in order to support the European Union policy on consumer health..

European Commission Joint Research Centre, IRMM, Retieseweg, B 2440 Geel, Belgium
J Chromatogr A 976:409-22. 2002..This new approach allows the separation of the proteins with high resolution by sodium dodecylsulfate-polyacrylamide gel electrophoresis and the sensitive determination of selenium in the protein bands...
How to overcome matrix effects in the determination of pesticides in fruit by HPLC-ESI-MS-MSK Bester
European Community Joint Research Centre, Institute for Reference Materials and Measurements IRMM, Geel, Belgium
Fresenius J Anal Chem 371:550-5. 2001..This effect was overcome by using a more complex clean-up, i.e. an additional size-exclusion step...
Uncertainty estimation on the quantification of major milk proteins by liquid chromatographyF Cordeiro
European Commission, Joint Research Centre, Institute for Reference Materials and Measurements, Geel, Belgium
Analyst 126:2178-85. 2001..3 up to 12.5% for individual protein concentration were found, whereas for total protein content, an overall combined relative standard uncertainty of 2.7% (liquid) and 3.3% (powdered samples) was achieved...
Study of the feasibility of using a pellicular anion-exchange column for separation of transferrin isoforms in human serum by HPLC with UV detectionM B de la Calle Guntiñas
European Commission, Joint Research Center, Institute for Reference Materials and Measurements, Retieseweg, 2440 Geel, Belgium
Anal Bioanal Chem 378:383-7. 2004..The whole chromatographic run, including re-equilibration of the column, took 35 min...
Determination of (fluoro)quinolone antibiotic residues in pig kidney using liquid chromatography-tandem mass spectrometry. I. Laboratory-validated methodB Toussaint
Institute for Reference Materials and Measurements, Joint Research Center, European Commission EC JRC IRMM, Geel, Belgium
J Chromatogr A 1088:32-9. 2005..The precision results showed mean repeatability and reproducibility coefficients of 7.4% and 11.8%, respectively. Limits of quantification much lower than the MRLs could be obtained...
