Analysis of Thiophene in Benzene using Nexis GC-2030

Introduction

Thiophene and other sulfur compounds are known to be linked to sulfur oxide generation during combustion, and as compounds associated with catalyst poisoning. Even very small quantities can have adverse effects, so the quality control of petroleum products requires trace analysis of sulfur compounds. In the petroleum refinement process, thiophene is eluted together with benzene. ASTM D 7011 specifies standards for the analysis of thiophene impurities in benzene. The FPD-2030 flame photometric detector, which is installed in Nexis GC-2030 gas chromatograph, has the world's highest level of sensitivity, thanks to the optimized nozzle shape and the advanced dual focus system. In the analysis of sulfur content in petroleum products, this detector provides high sensitivity and high stability. In this Application News, we describe the analysis of thiophene in benzene using Nexis GC-2030 gas chromatograph equipped with the FPD-2030.
