浩瀚色谱（山东）应用技术开发有限公司，采用HH-Sulfide硫专用毛细管柱柱分离法对直馏柴油中的硫化物进行分离，采用GC/MS予以定性，从分离物中检索出50余种环硫醚类硫化物和10余种二苯并噻吩类硫化物，并通过H2O2-HCOOH对直馏柴油中的含硫化合物(主要为二苯并噻吩类)进行了氧化，然后用苯抽提硫化物的氧化产物，GC/MS定性结果表明，二苯并噻吩类硫化物均相应的转化成它们的砜。采用GC/FPD对氧化前后的硫化物进行了定量分析。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used the HH Sulfide sulfur specific capillary column separation method to separate sulfides in straight run diesel. GC/MS was used for qualitative analysis, and more than 50 cyclic sulfide sulfides and more than 10 dibenzothiophene sulfides were retrieved from the separated products. The sulfur-containing compounds (mainly dibenzothiophenes) in straight run diesel were oxidized by H2O2-HCOOH, and the oxidation products of sulfides were extracted with benzene. The GC/MS qualitative results showed that dibenzothiophene sulfides were correspondingly converted into their sulfones. Quantitative analysis of sulfides before and after oxidation was conducted using GC/FPD.
