Oxygenates Analyzer
JAS Oxygenates Analyzer is a robust, reliable and sophisticated solution, which not only meets the ASTM D4815 requirements, but even exceeds these requirements!
- Methods : ASTM D4815, ASTM D5580
- Determination of oxygenated compounds including MTBE, ETBE, TAME, DIPE, and C1-C4 alcohols
- JAS Oxygenates Analyzer eliminates most of the interference from non-oxygenate hydrocarbons
- JAS Oxygenates analyzer includes JAS UNIS split-/splitless inlet, 10-port rotary valve, pre– and analytical column and FID
- JAS proprietary polar column reduces the interference of co-eluting olefins to almost zero.
Nowadays the oxygenates content is a substantial part of finished gasoline. Fuel oxygenates are added to help to reduce the use of harmful gasoline components and help to achieve a cleaner combustion.
Fuel oxygenates offer several benefits when added to gasoline, including:
- Reducing and displacing cancer-causing gasoline compounds such as Benzene, Toluene, Xylenes and Ethylbenzene.
- ‘Anti-knock’ agents to increase the octane number and decrease emissions by replacing organo-lead compounds.
- Reducing air toxic emissions year-around.
- National governments all over the world have specified the concentration levels of the individual oxygenates, which can be added to the gasoline. And these must be measured!
ASTM D4815 is frequently chosen as the standard method for the determination of these oxygenated compounds in gasoline.
The JAS Oxygenates in Gasoline Analyzer is a robust, reliable and sophisticated solution, which not only meets the ASTM D4815 requirements, but even exceeds these requirements!
The JAS Oxygenates Analyzer makes use of the famous JAS UNIS 500 S/SL inlet and a JAS proprietary polar column. This JAS proprietary polar column reduces the interference of co-eluting olefins to almost zero. As a result of this, the JAS Oxygenates Analyzer is proven to be a highly efficient, cost-effective and time-saving solution.
The JAS Report Generator software gives you the Mass% Oxygen Report.
Options
JAS has various options available to adapt and extend the JAS Oxygenates Analyzer to your specific application(s):
- Liquid sampling valves
- Various automated liquid samplers
- Alternative- or additional tuning for ASTM D5580
ASTM D5580, “Standard Test Method for Determination of Benzene, Toluene, Ethylbenzene, p/m-Xylene, o-Xylene, C9 and Heavier Aromatics, and Total Aromatics in Finished Gasoline”. This method makes use of the same hardware as ASTM D4815.
JAS REPORT GENERATOR SOFTWARE
This Software has the capability to automatically calculate physical properties such as BTU and specific gravity selected by the user after each analysis. Software uses the result table generated in ChemStationTM to calculate needed properties according to ISO 6976. A standard database for gases with flexibility for users to modify for special needed is included in the software. Additional conditions such as temperature and pressure can be edited as well.
- Provides Mass% Oxygen Report
- Calculations according to ISO 6976
- Expandable Compound Table
- Flexible Report Generation, allows customization
ASTM D4815 is ‘the method to use‘ when it comes to the analysis of oxygenated hydrocarbons in finished gasoline and other related
hydrocarbon matrices (liquids). Oxygenated compounds can be present as an ‘anti-knock‘ additive to increase the octane number and decrease the emissions by replacing organo-lead compounds. But oxygenated compounds can also be naturally present or being formed during catalytic processes such as polymer production.
