Sulfur compounds are ubiquitous in refining and petrochemical products • Variable in crude oils ranging from ppb level components to wt.% level S • Sweet vs. Sour Crude oil • Levels of sulfur in crude oil grow approximately 500 ppm per year, making …

Industry's first transmitter-style gas chromatograph capable of combining the measurement of natural gas energy content, hydrogen sulfide, speciation of total sulfur compounds to trace levels, and hydrocarbon dew point (HCDP) calculations in a single-analyzer solution

Gas chromatography with sulfur chemilumines-cence detection (SCD) provides a relatively quick means to identify and quantify sulfur compounds that are present in petroleum and petrochemical feeds and products, such as natural gas, ethylene, propylene, liquefied petroleum gases, solvents, gasoline, and diesel fuels. In many cases, it is suffi-

Because low sulfur concentrations (<50 ppm) are difficult to measure, SRI has enhanced our popular Multiple Gas Analyzer GC systems to simultaneously monitor low levels of sulfur compounds. The additional hardware required is an FPD/FID detector, which selectively detects sulfur down to the mid-ppb range, and a room-temperature sulfur-inert ...

Application: A specialized version of the SPB-1, this column was developed for analyses of sulfur gases and other volatile sulfur compounds. The column displays relatively low column bleed, which makes it compatible for use with sulfur-specific detectors.

Using Gas Chromatography for the Analysis of Ultra Low Sulfur Compounds in Gaseous Fuels. This article outlines the identification of speciated volatile sulfur-containing compounds in high methane content gaseous fuels such as natural gas, utilizing the innovative PAC SeNse detector.

Waters Empower chromatography data systems can now be used to control AOC-30 autoinjectors in Shimadzu Nexis™ GC-2030 systems and perform packed column analysis. Space-saving AOC-30 systems offer reliable and long-term performance, and support capillary/packed column analysis using only a single GC-2030 system.

The Agilent J&W DB-Sulfur SCD GC column with low bleed and exceptional inertness is specifically developed for sulfur compound analyses and optimized for GC/SCD.

In a sulfur chemiluminescence detector (SCD), samples (sulfur compounds) eluted from a GC column are injected into a burner to cause oxidation and reduction reactions. Then the samples (SO radicals) are sent to a reaction cell, where they collide with ozone, which generates light emission that is detected by a photomultiplier.

2024年7月12日 · 5.4 Analytical Methods— Gas chromatography (GC) is commonly used in the determination of fixed gas and organic composition of natural gas (Test Method D1945). Other standard ASTM methods for the analysis of sulfur in fuel gases include Test Methods D1072 and D4468 for total sulfur and Test Methods D4010 and D4884 for hydrogen sulfide.
