The OxyTracer analyzer, developed by PAC powered by AC, represents the state-of-the-art in the quantitative determination of oxygenated organic impurities.
Designed to operate on light hydrocarbon streams (C2-C3, LPG, naphtha, and gasoline), the system ensures compliance with the most stringent international industry standards.
The OxyTracer system is engineered to isolate and quantify polar compounds in complex hydrocarbon matrices with final boiling points up to 250°C (480°F). Thanks to the integration of flow-switching technologies, the system eliminates matrix interferences, allowing for selective analysis of target analytes.
Analytical Capabilities (Component Speciation)
The system allows for the accurate determination of the following classes of oxygenates:
- Alcohols: Methanol, Ethanol, n-Propanol, i-Propanol, n-Butanol, 2-Butanol, i-Butanol, t-Butanol, Allyl Alcohol
- Ethers: MTBE, ETBE, TAME, DIPE, Dimethyl Ether (DME), Diethyl Ether (DEE), Propyl Ether
- Ketones: Acetone, Methyl Ethyl Ketone (MEK)
- Aldehydes: Acetaldehyde, Propionaldehyde, Isobutylaldehyde, Butylaldehyde, Isovaleraldehyde, Valeraldehyde.
Specifications and Performance
- Sensitivity (LOD): Detection level less than 0.1 ppm (variable by method and matrix)
- Dynamic Range: Guaranteed linear response from 0.1 to 2000 ppm
- Time Efficiency: Complete analytical cycle (Run Time) in 25-30 minutes.
Regulatory Compliance
Fully compliant with ASTM D7423 and ASTM D7754 standard methods.
Distinctive Technical Feature
- Integrated Deans Switch Technology: the heart of the system is the Deans Switching principle, which enables excellent separation of sub-ppm oxygenates from the predominant hydrocarbon matrix. This architecture prevents contamination of the analytical column and detector, increasing system stability.
- Sample integrity and accuracy: the chemical and physical integrity of the sample is guaranteed by an advanced injection system that includes:
specific sampling valves for gases and liquids
backpressure regulators to prevent flash and partial evaporation, ensuring repeatable and accurate data - Dual-FID Configurability (Optional): to maximize operational flexibility and laboratory productivity: the analyzer can be equipped with a second flame ionization detector (FID), allowing for multi-channel configurations or parallel analysis.
Target Applications
- Quality control in refineries. Feed purity monitoring for polymerization units
- Certification of finished products (LPG, gasoline)
- Process analysis in petrochemical plants.
