3 Method summary
The low temperature research sample fine-grained to Φ0.5mm (35 mesh) or less, with isopropanol - n-hexane to extract a sample of three HBCD
Alkyl isomer (α-HBCD, β-HBCD and γ-HBCD), followed by liquid chromatography - mass spectrometry/mass spectrometer using the external standard method or the internal standard method (that is, with the same
Isotope dilution technique, after extracting a sample added three kinds of deuterated six HBCD d18-α-HBCD, d18-β-HBCD and d18-γ-HBCD in
Internal standard solution) isomer content was measured three kinds of hexa dodecane ring.
