For the analysis of chemical food contaminants and residues, gas chromatography (GC) is one of main analytical methodologies employed. As compared to HPLC, GC provides better separation efficiency by the use of hight efficiency capillary columns and specific detectors like electron-capture detector (ECD) or nitrogen-phosphorus detector (NPD). After the 80‘s decade GC has been traditionally combined with MS, and the availability of relative affordable benchtop GC-MS instruments, gave preference to GC analysis of multicomponent contaminant and residue analysis.
With the MRPL approach the European Commission has proposed a temporary measure to address urgent problems related to prohibited substances particularly when it comes to third country trade. 24 Jorge Barbosa, Simone Ferreira, Alberto Canelas Pais et al. 9. SAMPLE PREPARATION METHODS Sample preparation is the process of extracting chemical residues from a sample and the subsequent purification of the extract to isolate the residues of interest and remove any matrix interferents that may affect the detection system.
