This part of GB/T 3780 specifies the use of gas chromatography-mass spectrometry (GC-MS) to determine the content of polycyclic aromatic hydrocarbons (PAHs) in carbon black
Methods.
This section applies to the qualitative and quantitative testing of 18 polycyclic aromatic hydrocarbons for rubber carbon black and pigment carbon black.
2 Normative references
The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article
Pieces. For undated references, the latest version (including all amendments) applies to this document.
GB/T 3778 Carbon black for rubber

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Polycyclic aromatic hydrocarbons; PAHs
A hydrocarbon containing two or more benzene rings in the molecule.
Note. According to the connection mode of the benzene ring, polycyclic aromatic hydrocarbons can be divided into three types. polyphenyl substituted aliphatic hydrocarbons, biphenyl and fused polycyclic aromatic hydrocarbons.
4 Principle
The sample is mixed with toluene to extract polycyclic aromatic hydrocarbons in an ultrasonic water bath. After cooling, the components to be tested are obtained by membrane filtration.
Measured by GC-MS and quantified by internal standard method.
5 Reagents and materials
5.1
Toluene, above analytical grade.
5.2
Internal standard substance 1, commercially available certified octa-deuterated naphthalene (Naphthalene-d8), used to calibrate the No. 1 PAHs in Appendix A.
5.3
Internal standard substance 2, commercially available certified deuterated pyrene (Pyrene-d10), or deuterated anthracene (Anthracene-d10), or deuterated phenanthrene (Phenan-d10) threne-d10), used to correct the PAHs No. 2 to No. 10 in Appendix A.
5.4 Internal standard 3, commercially available certified Perylene-d12, or Benzo(a)pyrene [Benzo(a)pyrene-d12], three
Triphenyl-benzene is used to calibrate PAHs No. 11 to No. 18 in Appendix A.
