The determination of 2,3,7,8-tetrachlorodibenzo-p-dioxin in biological extracts by gas chromatography mass spectrometry.
Using both gas chromatography low resolution mass spectrometry and gas chromatography high resolution mass spectrometry, 2,3,7,8-tetrachlorodibenzo-p-dioxin at the part per trillion level may be determined in pre-concentrated extracts of bovine fat, liver and milk; human milk; rats; rice; grass; soil and water. Criteria are set forth for the objective determination of detection limit, signal and noise as applied to these determinations.
