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.
• Ultra-high purity fittings and regulators.
• Cryogenic cooling may be used to separate argon and oxygen.
• Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
