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.
- Fused silica lined tubing protects sample integrity.
- Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
- On-board vaporizer converts liquid carbon dioxide to gas phase prior to injection for more repeatable analysis.
- Can be configured for both liquid and gas sample analysis.
