名稱:毛細管柱
規格:30 m(長)×0.32 mm(內徑)×0.25 μ m(膜厚),固定相為 100%二甲基聚硅氧烷或(5%-苯基)-甲基聚硅氧烷為填料的石英彈性毛細管柱,或能達到分離要求的同類毛細管柱。
型號:SE-54
應用:煤焦油苯、甲苯、苯酚、萘、芴、菲、蒽、芘的含量測定氣相色譜法
本標準規定了煤焦油苯、甲苯、苯酚、萘、芴、菲、蒽、芘的含量測定的原理、試劑及材料、儀器和設備、樣品、試驗步驟、結果計算、精密度。
本標準適用于煤的加氫氣化工藝產生的煤焦油的測定,其他煤轉化工藝產生的煤焦油對應的蒸餾產物可參照執行。
用二氯甲烷溶解煤焦油,在該溶液中定量加入內標物4-溴氟苯,利用商品化毛細管色譜柱進行完全分離。用微量注射器直接進樣,試樣被載氣帶入色譜柱,采用氫火焰離子化檢測器(FID)分析苯、甲苯、苯酚、萘、芴、菲、蒽、芘的含量。用色譜工作站,將試樣目標物與標準樣品目標物的色譜峰對比,根據保留時間對各目標物定性,利用內標法對各目標物準確定量。

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 statio
nary 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 co
ntent 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 correspo
nding distillation products of coal tar produced by other coal co
nversion 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 co
ntent of benzene, toluene, phenol, naphthalene, fluorene, phenanthrene, anthracene, and pyrene was analyzed using a hydrogen flame io
nization 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.
