名稱：填充柱
規(guī)格：Φ4mm*3m
型號：10%阿匹松L/Chromosorb w-AW DMCS
粒度：60-80目
應用：焦爐煤氣中苯測定 氣相色譜法

浩瀚色譜（山東）應用技術(shù)開發(fā)有限公司從苯的物理性質(zhì)著手,針對在煉焦行業(yè)焦爐焦氣中苯含量的測定且目前的測定方法較毒,重現(xiàn)性不理想,樣品測定的時間過長,改變色譜條件(主要是色譜柱)后,可以不用溶劑吸收,直接用玻璃注射器取樣后直接進樣后進行測定,新的方法更迅速,準確,,此方法可以扣除在吸收樣品過程中產(chǎn)生的誤差,還能消除用微量進樣器進樣時產(chǎn)生的誤差,原方法測定前每次吸收煤氣中的苯需用100—300ml環(huán)己酮,現(xiàn)不用環(huán)己酮,節(jié)省了環(huán)己酮用量且減少了廢液處置及降低了環(huán)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
