Determination of PCDD/Fs and dioxin-like PCBs in food and fe

发布时间：2025-06-25 23:07

　　 A method was developed on a gas chromatograph coupled to a triple quadrupole mass spectrometer（GC-MS/MS） for trace level determination of polychlorinated dibenzo-p-dioxins/dibenzofurans（PCDD/Fs） and dioxin-like polychlorinated biphenyls（DL-PCBs） in food and feed. The results demonstrated good sensitivity and repeatability for PCDD/Fs and DL-PCBs at an extremely low level(10 pg mL^-1 for 2,3,7,8-TCDD/F), as well as wide linear response of over 3 or 4 orders of magnitude in concentration...
