Test method for polycyclic aromatic hydrocarbons in rubber
Caution - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions
It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set forth in the relevant national regulations.
1 Scope
This standard specifies the determination of 16 polycyclic aromatic hydrocarbons in rubber shoes by gas chromatography-mass spectrometry.
This standard is applicable to the detection of 16 polycyclic aromatic hydrocarbons in rubber materials.
2 principle of the method
Samples with the internal standard and toluene mixed, ultrasonic extraction, if necessary, then by solid phase extraction column purification, concentration, constant volume, with gas chromatography - quality
(GC/MSD), and the method was selected by selective ion detection.
3 reagents and materials
3.1 toluene (chromatographic purity).
3.2 n-hexane (chromatographic purity).
3.3 Dichloromethane (chromatographic purity).
3.4 N-Hexane Dichloromethane. N-Hexane and Dichloromethane were prepared in a volume ratio of 1. 1.
3.5 silica gel solid phase extraction column. 2g, 6mL or equivalent, before use with n-hexane infiltration.
3.6 40 mL vial with PTFE cap.
3.7 needle filter. 0.45μm organic filter.
3.8 16 polycyclic aromatic hydrocarbon reference materials (see Appendix A). purity ≥96%.
3.9 polycyclic aromatic hydrocarbons mixed standard solution, 100mg/L. accurately weighed the amount of polycyclic aromatic hydrocarbons standard material, with n-hexane configuration to the required concentration
Of the standard solution, you can also buy a commercially available mixed standard solution.
3.10 polycyclic aromatic hydrocarbons mixed standard working solution, 5mg/L. take 0.5mL polycyclic aromatic hydrocarbon mixed standard solution (3.9) dissolved in n-hexane,
To 10 mL.
3.11 polycyclic aromatic hydrocarbons mixed standard working solution, 1mg/L. take 0.1mL polycyclic aromatic hydrocarbon mixed standard solution (3.9) dissolved in n-hexane,
To 10 mL.
3.12 Internal standard.
a) naphthalene D8 standard substance. purity ≥ 96%;
b) anthracene D10 standard substance. purity ≥ 96%;
c) 1,3,5-triphenyl benzene standard material. purity ≥ 96%.
3.13 internal standard solution, 100mg/L. accurately weighed the amount of internal standard with toluene prepared into the required concentration of the internal standard solution.
3.14 internal standard use of liquid, 1mg/L. take 1.0mL internal standard solution (3.13) dissolved in n-hexane, constant volume to 100mL.
3.15 toluene internal standard use of liquid, 100μg/L. 0.1mL internal standard solution (3.13) dissolved in toluene, constant volume to 100mL.
