| Popis: | A versatile high-resolution gas chromatographic system utilizing universal sulfur chemiluminescence detection (USCD) coupled with flame ionization detection (FID) was optimized for the determination of sulfur components in light petroleum process streams. The normalized area precision for individual species was ca. 1.5–6.0% (relative standard deviation) for the major components at a total 1.7 (w/w) of sulfur level. The system is capable of speciating sulfur components in petroleum process streams containing 0.01–3.13% (w/w) of sulfur. The linear relationship (r2 = 0.998) between the USCD absolute sulfur response and the total sulfur content of several samples of petroleum process streams clearly indicated that, in addition to speciation, total sulfur can simultaneously be determined with reasonable accuracy. |
