Oxygenates Analyzer
Accurate, reliable analysis of oxygenated compounds in modern fuels.
Overview
Modern gasoline formulations include a significant amount of fuel oxygenates, which are added to promote cleaner combustionand reduce harmful components. These oxygenates not only enhance performance but also help meet stringent environmental and regulatory standards.
Fuel oxygenates offer multiple benefits when blended into gasoline:
- Reduce or replace cancer-causing compounds such as benzene, toluene, xylenes, and ethylbenzene
- Act as anti-knock agents, raising the octane number and replacing toxic organo-lead additives
- Reduce air-toxic emissions throughout the year
Because of their importance, national and international regulations specify the maximum allowable concentrations of each oxygenate — and accurate measurement is essential.
The ASTM D4815 method is the most widely used standard for determining these oxygenated compounds in gasoline.
Technical Highlights
The JAS Oxygenates in Gasoline Analyzer is a robust, reliable, and sophisticated solution that not only meets but exceeds ASTM D4815 performance requirements.
Key design features include:
- JAS UNIS 500 S/SL inlet system for consistent sample introduction
- Proprietary JAS polar column that virtually eliminates interference from co-eluting olefins
- High analytical efficiency, delivering accurate, cost-effective, and time-saving results
- Integrated JAS Report Generator software providing automated Mass% Oxygen reports
Available Options
To adapt the analyzer for specific laboratory needs, JAS offers:
- Liquid Sampling Valves
- Automated Liquid Samplers
- Additional or alternative tuning for ASTM D5580
ASTM D5580 – Standard Test Method for the Determination of Benzene, Toluene, Ethylbenzene, p/m-Xylene, o-Xylene, C₉ and heavier aromatics, and total aromatics in finished gasoline – utilizes the same hardware as ASTM D4815, ensuring seamless multi-method compatibility.
