GB/T 24893-2010/ISO 15753.2006 Animal and vegetable fats Determination of Polycyclic Aromatic Hydrocarbons 1 Scope This standard specifies the determination of 15 PAHs animal fats relevant terms and definitions, principles, again by HPLC Agents, equipment, pretreatment methods of general animal fat, coconut oil, and pre-treatment methods short chain fatty acids containing vegetable oil, high performance liquid chromatography Spectral analysis, results are shown and precision. This standard applies to general animal fats and coconut oil was measured and short chain fatty acids containing vegetable oils polycyclic aromatic hydrocarbons. This standard does not apply to the more volatile components of quantitative naphthalene, acenaphthene and fluorene analysis, and palm oil and olive pomace oil Polycyclic Aromatic Hydrocarbons Determination. PAHs remaining quantitative detection limits were 0.2μg/kg. 2 Normative references The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 15687 animal and plant oils prepared sample (GB/T 15687-2008, ISO 661.2003, IDT) 3 Terms and Definitions The following terms and definitions apply to this standard. 3.1 A compound containing two or more fused aromatic rings. According to the standards prescribed conditions determination of its content in milligrams per kilogram (Mg/kg) meter. Note. usually contain polycyclic aromatic hydrocarbons can be divided into two to four aromatic rings of light PAHs and five and five or more aromatic rings weight PAHs. Example. Light PAHs include. naphthalene (CASRN [91-20-3]), acenaphthylene (CASRN [83-32-9]), acenaphthylene (CASRN [208-96-8]), fluorene (CASRN [86-73 - 7]), anthracene (CASRN [120-12-7]), the Philippines (CASRN [85-01-8]), fluoranthene (CASRN [206-44-0]), "(CASRN [218-01-9 ]), benzo (Rao) anthracene (CASRN [56-55-3]), pyrene (CASRN [129-00-0]). Weight PAHs include. benzo (Rao) pyrene (CASRN [50-32-8]), benzo (Chou) fluoranthene (CASRN [205-99-2]), benzo (k) fluoranthene (CASRN [207 39-5]). Principle 4 Polycyclic aromatic hydrocarbons in the sample with acetonitrile - acetone mixture was extracted, followed by extraction with C18 reverse phase column and Florisil bonded stationary phase Column purified by high performance liquid chromatography (HPLC) separation, fluorescence intensity was measured at different excitation and emission wavelengths measured for various multi Ring aromatics content. 5 Reagents Warning. be aware of dangerous goods rules of operation, the operation should follow the technical, organizational and personal safety measures. Unless otherwise stated, use only analytical reagent. GB/T 24893-2010/ISO 15753.2006 ......
