GCxGC COUPLED TO FAST SCANNING QUADRUPOLE MS FOR TRACE ANALYSIS OF POPs

The paper describes preliminary data for the use of comprehensive two-dimensional gas chromatography (GCxGC) coupled to fast scanning quadrupole mass spectrometry (MS) for the measurement of dioxins and PCBs in biological samples. Electron impact (EI) and negative chemical ionization (NCI) are used and evaluated in terms of quantification using isotope dilution.
