EUROLAB laboratory provides testing and compliance services within the scope of ASTM D8143 standard. The ASTM D8143 standard covers the qualitative and quantitative determination of the EU-8 polycyclic aromatic hydrocarbons (PAH) list on carbon black. The procedure includes Soxhlet extraction with toluene followed by extract analysis using gas chromatography with mass spectrometry (GC/MS).
This method is not designed to test for US Food and Drug Administration (FDA 21 CFR 178.3297) compliance of carbon blacks used for indirect food contact applications.
This test procedure is used to determine individual concentrations of EU-8 listed PAH compounds extracted from carbon black by means of a Soxhlet extractor with toluene.
organic compounds consisting of chemical structures of alternating single and double bonds having a ring-like structure (for example, benzene) without polycyclic aromatic hydrocarbon, PAH, n-heteroatom or other substituents; the rings are often fused to form larger chemical structures.
PAH occurs naturally in oil, coal and tar deposits; produced by incomplete combustion of hydrocarbons; and occurs in many other products and processes.
A portion of carbon black is extracted with Soxhlet with toluene for 48 hours. The extract is concentrated and then analyzed for specific PAH compounds by mass spectrometry (GC/MS) and gas chromatography. Each PAH compound is measured separately using internal and external standards.
This test procedure is used to determine individual concentrations of EU-8 listed PAH compounds extracted from carbon black by means of a Soxhlet extractor with toluene.
Values stated in SI units will be accepted as standard. No other units of measurement are included in this standard.
This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
Our organization, EUROLAB, provides standard test method services for the determination of the EU-8 carbon black PAH compounds list, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies. Provides testing services within the scope of ASTM D8143 standard.
