Abstract

Abstract High-performance liquid chromatography (HPLC) has been used to cleanup chicken liver and wood shaving samples for their subsequent analysis by mass spectrometry (MS). With a reversed-phase system and discrete fraction collection, hexa-, hepta-, octachlorodibenzodioxin and octachlorodibenzofuran have been detected in wood shavings and chicken livers to a lower level of 25 pg/g. With the use of HPLC as a cleanup tool, the MS determination both on the probe and by gas chromatography-MS resulted in an improved peak shape and a stronger more accurate signal for the dioxins and furans.
