The GC Zero Air generators produce dry and hydrocarbon/NOx-free air, using air from oil-free compressors, thus avoiding the need to use traditional bottles that are often complex to change.

The ergonomic, compact and silent design makes the Ultra-Zero Air series generators the ideal solution for the following analytical applications: GC-FID, GC-NPD, GC-FPD, GC-PFPD, THA.

Benefits

Better detector performance
The reduction of hydrocarbons, including methane, and carbon monoxide to < 0.1 ppm, as well as NOx to < 1 ppm, decreases the background noise level and gives the baseline much better stability, considerably increasing detector sensitivity and ensuring precise analytical results.

Easy installation
Just connect a suitable oil free compressor (optional) to almost immediately have air at the right grade.
To save bench space, the unit can be easily installed on the lab wall.

Lab safety
No more bottles in the lab and expensive pipelines for air
distribution.

Save money
The unit only requires connection to a suitable oil free compressor
and the mains: the investment can be paid back in less than a year.

Improved lab efficiency
Continuous operation 24 hours a day cuts dead times for gas bottle changeover and avoids the need for tedious instrument
recalibrations.

Operating diagram

Ultra-Zero Air generators use fi ve steps to transform ambient air into analytical grade air.
Step 1: Pre-filtration.
The external oil-free compressor delivers air through a high-efficiency filter that traps any particles that may damage the system.
The fi lter has an automatic purge system, and traps oil, water and any other particles larger than 5 microns in size.

Step 2: Drying and trapping.
Residual moisture and CO2/CO molecules are removed by a dual active carbon trap.

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

Step 4: HC and CO trapping.
The air leaving the fi lter enters a high-temperature platinum catalyser, which through oxidation eliminates hydrocarbon
molecules down to < 0.1 ppm.

Step 5: Final filtration.
A high-effi ciency fi lter is used to prevent any kind of particles from entering the instrument.

External compressor (option): following an agreement with a leading manufacturer operating a sales and service network in many cities throughout Italy and the world, DBS can supply the right “oil free” compressor for different flow requirements.
