Scope

This standard specifies the method for determining 17 chlorine-substituted polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzo-furans (PCDFs) (hereinafter referred to as PCDD/Fs) and 12 dioxin-like polychlorinated biphenyls (DL-PCBs) (see Tables A.1 and A.2) in feed using isotope dilution-high resolution gas chromatography/high resolution mass spectrometry.
This standard is applicable to feed raw materials, compound feed, concentrated feed, supplementary feed, premix feed, and feed additives.
The detection limits of PCDD/Fs and DL-PCBs in feed determined by this standard method are shown in Table B.1.
