名称：填充柱
规格：Φ4mm*3m
型号：10%阿匹松L/Chromosorb w-AW DMCS
粒度：60-80目
应用：焦炉煤气中苯测定 气相色谱法

浩瀚色谱（山东）应用技术开发有限公司从苯的物理性质着手,针对在炼焦行业焦炉焦气中苯含量的测定且目前的测定方法较毒,重现性不理想,样品测定的时间过长,改变色谱条件(主要是色谱柱)后,可以不用溶剂吸收,直接用玻璃注射器取样后直接进样后进行测定,新的方法更迅速,准确,,此方法可以扣除在吸收样品过程中产生的误差,还能消除用微量进样器进样时产生的误差,原方法测定前每次吸收煤气中的苯需用100—300ml环己酮,现不用环己酮,节省了环己酮用量且减少了废液处置及降低了环境污染.

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
