Description
Chemtron 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.
