Determination of naphthalene content in coke oven gas by capillary gas chromatography

Determination of naphthalene content in coke oven gas by capillary gas chromatography Details:



Name: capillary column



Stationary phase: 5% phenyl-95% dimethyl polysiloxane



Specification: 30m * 0.32mm * 0.25um



Model: HH-5

Application: coke oven gas -- Determination of naphthalene content -- Gas chromatography




This document specifies the principle, instrument and materials, sampling, analysis steps, result calculation, precision and safety precautions of gas chromatographic determination of naphthalene content in coke oven gas. This document is applicable to the determination of naphthalene content in coke oven gas



The content of naphthalene in coke oven gas is determined by capillary gas chromatography in Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. HH-5 (cross-linked) capillary column was selected, xylene was used as absorbent, and the retention time was used for qualitative analysis and internal standard method for quantitative analysis. Compared with the national standard picric acid method and gas chromatography method, the sensitivity is greatly improved, the analysis time is shortened from 3-4 hours to 30 minutes, the operation is simple, the accuracy and precision are good, and it can be directly used for the analysis and control of naphthalene content in coke oven gas.
