Fast Hydrocarbon and Sulfur Simulated Distillation Using the Agilent Low Thermal Mass (LTM) System on the 7890A GC and 355 Sulfur Chemiluminescence Detector
نویسنده
چکیده
A fast multielement simulated distillation method (SimDis) based on Low Thermal Mass (LTM) column technology is described. The LTM system technology using resistive heating allows rapid temperature programming with extremely fast column cooldown. Significantly shortened analytical cycle times as compared to conventional air bath GC ovens are achieved. The method combines hydrocarbon SimDis with an FID with sulfur SimDis using the Agilent 355 sulfur chemiluminescence detector (SCD) in a series configuration. The results show that the LTM method produces a run time for both hydrocarbon and sulfur boiling point distribution at least six times shorter than the conventional ASTM D2887 procedure [1]. The results agree with the specification in ASTM D2887 for the reference gas oil checkout sample.

Simultaneous Analysis of Greenhouse Gases by Gas Chromatography
Two analytical methods based on the Agilent 7890A GC system are developed for simultaneous analysis of methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O) in air samples. Each system has its own features to meet different requirements of greenhouse gases analyses. Both systems can easily be expanded to determine sulfur hexafluoride (SF6). Results from both methods demonstrated high sensiti...
متن کاملAutomated Clean-up for Mineral Oil (Hydrocarbon Oil Index) Analysis using the Agilent 7696A Sample Prep WorkBench
Mineral oil (or Hydrocarbon oil) in water samples is determined by liquid-liquid extraction, followed by a clean-up step on Florisil, and GC-FID analysis. Using the Agilent 7696A Sample Prep WorkBench system, drying and clean-up of samples obtained after liquid-liquid extraction can be automated. High recoveries and excellent reproducibility are obtained for the mineral oil fraction, while the ...
متن کاملFractional Distillation Process Utilized to Produce Light Fractional Fuel from Low Density Polyethylene (LDPE) Waste Plastic
Plastics are not easily biodegradable; and because of these characteristics they can remain under landfill and water for a very long period of time. All over the world only 6% of waste plastics are recycled and the rest of all waste plastics are dumped into landfills. An experiment was conducted in a laboratory scale batch process under Labconco’s fume hood utilizing low density polyethylene (L...
متن کاملFast Simulated Distillation Based on Agilent 6890N GC
A rapid simulated distillation method is described for analysis of petroleum fractions boiling within the range of ASTM D2887 [1]. The method employs an Agilent 6890N gas chromatograph (GC) equipped with a split/splitless inlet, flame ionization detector (FID), oven insert, and 3-meter 180-μm id capillary column. A SIMDIS software package is partially integrated into the GC ChemStation for data...
متن کاملChemiluminescence Detector (SCD): Sulfur Speciation in Grapefruit Juice
The ability to measure sulfur compounds at trace levels is extremely important in the food, flavor, and beverage industries. Sulfur compounds, especially volatile ones, impact flavor and aroma both positively and negatively, although they are more often associated with off-flavors or odors. Interest concerning the measurement and speciation of sulfur compounds in the citrus industry is growing....
