Coal tar benzene, toluene, phenol, naphthalene fluorene phenanthrene pyrene
Coal tar benzene, toluene, phenol, naphthalene fluorene phenanthrene pyrene details:

Name: Capillary Column
Specification: 30 m (length) × 0.32 mm (inner diameter) × 0.25 μ m (film thickness), the stationary phase is 100% dimethyl polysiloxane or (5%-phenyl)-methyl polysiloxane Filled silica elastic capillary column, or similar capillary column that can meet the separation requirements.
Model: SE-54
Application: Determination of the content of coal tar benzene, toluene, phenol, naphthalene, fluorene, phenanthrene, anthracene and pyrene by gas chromatography


This standard specifies the principles, reagents and materials, instruments and equipment, samples, test procedures, results calculation, and precision for the determination of coal tar benzene, toluene, phenol, naphthalene, fluorene, phenanthrene, anthracene, and pyrene.
This standard applies to the determination of coal tar produced by the hydrogenation process of coal, and the corresponding distillation products of coal tar produced by other coal conversion processes can be implemented by reference.
The coal tar is dissolved in dichloromethane, the internal standard 4-bromofluorobenzene is quantitatively added to the solution, and a commercial capillary chromatographic column is used for complete separation. The sample was injected directly with a micro syringe, and the sample was carried by the carrier gas into the chromatographic column, and the content of benzene, toluene, phenol, naphthalene, fluorene, phenanthrene, anthracene, and pyrene was analyzed using a hydrogen flame ionization detector (FID). Use the chromatographic workstation to compare the chromatographic peaks of the sample target and the standard sample target, qualitatively identify each target according to the retention time, and accurately quantify each target using the internal standard method.
