VICI DBS GT Ultra-Zero Air Generators are designed to supply ultrapure hydrocarbon-free zero air for GC-FID applications. Catalytic oxidation technology eliminates hydrocarbons to

GT Zero Air features:

  • Flow rate from 1.5 to 30 l/min
  • Pressure up to 6.5 bar (95 psig)
  • Zero air purity
  • Minimal maintenance
  • 2 year standard warranty

OPERATING PRINCIPLE
Ultra-Zero Air generators use five 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: DRYING AND TRAPPING
Residual moisture and CO/CO2 molecules are removed by a dual active carbon trap.

STEP 3: NOx, SOx, O3
A special scrubber removes these specific molecules.

STEP 4: 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 5: 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 NOx to < 1 ppm and 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.
