Coke oven gas Determination of benzene content Gas chromatographic method

Coke oven gas - Determination of benzene content - Gas chromatographic method - Details:



Name: Filled column

Specifications: Φ 4mm*3m

Model: 10% aspirin L/Chromosorb w-AW DMCS

Particle size: 60-80 mesh

Application: determination of benzene in coke oven gas by gas chromatography



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. starts from the physical properties of benzene. Aiming at the determination of benzene content in coke oven coke gas in coking industry, the current determination method is toxic, the reproducibility is not ideal, and the sample determination time is too long. After changing the chromatographic conditions (mainly the chromatographic column), you can directly take samples with a glass syringe and directly inject samples for determination without solvent absorption. The new method is more rapid, accurate, and reliable, This method can deduct the errors generated in the process of sample absorption, and also eliminate the errors generated in the process of sample injection with a micro sampler. Before the original method was used to determine benzene in the coal gas, 100-300ml cyclohexanone was required for each absorption. Now cyclohexanone is not used, which saves the amount of cyclohexanone, reduces waste liquid disposal and reduces environmental pollution
