General description

This ChromGas zero air generator incorporates three stages:
• A 0.5 mm coalescing inlet filter removes particles, oil, and water
• A heated catalyst removes hydrocarbons
• A 0.01 mm cellulose fiber outlet filter removes residual particulate material from the product air stream
A hazard-free and economical alternative to high pressure gas cylinders, this unit should pay for itself in a year or two.

Features/Benefits
• Eliminates need for expensive gas cylinders
• Compact; requires less than one square foot of bench space
• Can be used anywhere that an electrical supply is available
• Only requires an upstream compressed air source

Maintenance
• Clean the inlet and outlet filters every six months
• Change the inlet and outlet filters every two years

Application

Catalytic Zero air generator may be used to measure zero air count rates after field measurements, to determine atmospheric concentrations of volatile organic compound using On-line proton transfer reaction-mass spectrometry (PTR-MS). It may also be used to obtain volatile organic compound-air which could be used to dilute the standard gas to 50 ppb required to calibrate PTR-MS.
