Typical Chromatogram

Key Features and Benefits

• Oxygen will be detected by the PDHID but will not be quantified. For accurate trace oxygen analysis an external oxygen sensor is required.
• Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
• Cryogenic cooling may be used to separate argon and oxygen.
• On-board vaporizer converts liquid to gas phase prior to injection for more repeatable analysis.
• Fused silica lined tubing ensures repeatability and the lowest detection limits.
• PDHID and TCD in series provides wide detection range.
• 11 minute analysis time.
