Where is the AA gas purifier normally used?

All atomic absorption spectrophotometers that utilize compressed air as an oxidant gas and acetylene as a fuel gas.

What does the AA gas purifier do?

• Provides a cost effective alternative to using high-pressure compressed air cylinders as the oxidant gas supply
• Allows the user to utilize the convenience of a house compressed air system or compressor rather than purchasing high-pressure compressed air cylinders.
• Effectively eliminates all inherent house compressed air oil, water, and particles to less than 1.0 ppm.
• Purifies acetylene gas by effectively removing all acetone and particles to less than 1.0 ppm.
• Allows the user to use a greater percentage of the acetylene gas cylinder without the worry of damaging acetone getting into the instrument.
• Allows the user to reduce the annual total number of acetylene cylinders used at the instrument.
• Eliminates the background noise from iron oxides.

How does the AA gas purifier operate?

• The purifier consists of two independent filtration systems conveniently packaged into simple wall-mountable package.
• Dual stage high-efficiency coalescing filtration effectively purifies the compressed air oxidant prior to entering the instrument.
• Single stage filtration effectively purifies the acetylene fuel supply.
• Integral automatic draining systems remove collected oil and water from the purifier without operator attention.
• Acetone aerosols are blocked and vaporize to pass harmlessly through the instrument.

Why should an AA gas purifier be used?

• Effectively prevents damage to the AA burner head and prevents the associated downtime, instrument service calls and burner head replacement costs.
• Effectively prevents damage to the AA gas control box and prevents the associated downtime, instrument service calls and gas control box replacement costs.
• Older AA spectrophotometers can be difficult to get parts for, the AA purifier will help to protect what you have.
• Immediate payback instead of purchasing compressed air tanks.

How many instruments will an AA purifier supply?

Parker recommends one purifier installed for each AA instrument.

What is required for maintenance on the AA purifier system?

Parker recommends replacement of all filter cartridges once a year, order Parker maintenance kit part number 73065

What is required if an air leak occurs?

• Inspect the base of the two rear larger filter assemblies and verify if an automatic drain is closed.
• Verify that the incoming compressed air pressure is greater than 15 psig.
• Order and install automatic drain kit, part number 21552. Two drain kits may be required.

My oxidant gas is normally nitrous oxide for high temperature work, can I run this gas through the AA purifier system?

No, contact Parker technical services at 800-343-4048 for alternate type 95A filter solution.

I have a special AA purifier system part number 73-099 how do I get parts for it?

This is a special product contact Parker technical services at 800-343-4048 direct.

How safe is the AA purifier system?

There is nothing corrosive in the system and the system is pre-engineered around the strict CGA guidelines to manage acetylene. The purifier has integral back-flash Arrestor for safety and appropriate left threaded CGA fittings.
