Typical Chromatogram
Key Features and Benefits
- Oxygen will be detected but will not be quantified. For accurate oxygen analysis an external oxygen sensor is required.
- Internally purged valves for the PDHID analysis
- Fused silica lined tubing ensures repeatability and the lowest detection limits.
- On-board vaporizer converts liquid propylene to gas phase prior to injection for more repeatable analyses
