PRODUCT OVERVIEW

Description

Chemtron GT Ultra-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. 

The GT Zero Air Generator removes CO, CO2, NOX, SOX, and water vapor, making it ideal for demanding applications such as TOC, continuous emissions monitoring, and process control applications.

GT 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, <5 ppm CO2, <0.1 ppm CO, <0.1ppm NOX and SOX
* 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.
