High-Precision Low Level Oxygenates Analysis
Oxygenated components such as alcohols, ethers and ketones can be present in hydrocarbon streams at low ppm or sub-ppm levels. Even at these concentrations, oxygenates can significantly reduce catalyst lifetime and negatively impact downstream processing. In addition, environmental and product quality regulations increasingly require accurate monitoring of oxygenates at low concentration levels.
The GAS Low Level Oxygenates Analyser provides a dedicated GC-based solution for the analysis of oxygen-containing components in liquid hydrocarbons according to ASTM D7423, ASTM D7754 and UOP 960. Built on proven Thermo Trace GC 1600 technology, the analyser combines highly selective capillary separation with robust liquid injection and integrated backflush to deliver reliable, repeatable results with high uptime and low maintenance.
Applications
- Supported methods:
ASTM D7423, ASTM D7754 and UOP 960. - Low Level Oxygenates in Hydrocarbon Streams
Analyse alcohols, ethers and ketones with boiling points up to 100 °C in hydrocarbon matrices with final boiling points below 250 °C.
- Feedstock Quality Control
Detect trace oxygenated impurities that can poison catalysts and reduce process efficiency.
- Gasoline and Light Product Testing
Perform low-level oxygenates analysis in gasoline and similar light petroleum products.
- Samples Containing Ethanol (1–15%)
Analyse oxygenates in ethanol-containing samples according to ASTM D7754 using extended pre-column configuration.
- Gas, Liquid and LPG Sample Analysis
Support liquid, gas and liquefied gas samples using SSL, GSV or LSV injection with optional Sample Securitiser.
Benefits
- Low ppm and Sub-ppm Detection
Achieve minimum detectability down to 0.1 ppm for individual oxygenated components. - Highly Selective Separation
Dedicated Lowox capillary column separates oxygenates from complex hydrocarbon matrices. - Integrated Backflush Design
Built-in backflush removes high-boiling components without additional valves, protecting the analytical column. - Flexible Injection Techniques
Combine SSL, GSV and LSV injection methods in a single analyser for maximum application flexibility. - Robust, Modular GC Platform
Based on Thermo Trace GC 1600 with InstantConnect injectors and detectors for high uptime and low maintenance.
