GC Zero Air Generator

VICI DBS GC Zero Air Generators are designed to supply ultrapure hydrocarbon-free zero air for GC-FID applications. Catalytic oxidation technology eliminates hydrocarbons to <0.1ppm, resulting in a flat, stable baseline, increased sensitivity, and repeatable analysis.

GC Zero Air features:
• Flow rate from 1.5 to 30 l/min
• Pressure up to 6.5 bar (95 psig)
• Zero air purity <0.1ppm HC
• Minimal maintenance
• 2 year standard warranty

OPERATING PRINCIPLE
Zero Air Generators use three steps to transform ambient air into analytical grade air.

STEP 1: PRE-FILTRATION
An external oil-free compressor delivers air through a high efficiency filter that traps any particles that may damage the system. The filter, which has an automatic purge system, traps oil, water, and any particles larger than 5 microns in size.

STEP 2: HC AND CO TRAPPING
The air leaving the filter enters a high temperature platinum catalyzer, which eliminates hydrocarbon molecules down to < 0.1 ppm through oxidation.

STEP 3: FINAL FILTRATION
A final pass through a high-efficiency filter prevents any kind of particles from entering the instrument.

BENEFITS

BETTER DETECTOR PERFORMANCE
The reduction of carbon monoxide and hydrocarbons (including methane) to < 0.1 ppm decreases the background noise level and gives the baseline much better stability, increasing detector sensitivity considerably and ensuring precise analytical results.

EASY INSTALLATION
Just connect a suitable oil-free compressor (optional). To save bench space, the unit can be easily wall-mounted.

LAB SAFETY
No more bottles in the lab and expensive pipelines for air distribution.

SAVE MONEY
All that the unit requires is a connection to a suitable oil-free compressor and the mains.  Typically the investment is recovered in less than a year.

IMPROVED LAB EFFICIENCY
Round the clock continuous operation maximizes lab productivity, eliminating dead time for gas bottle changeover and avoiding the need for tedious instrument recalibrations.

The following option is available:
• Outlet valve
