Zero Air generator

The AirGen series ZA TOTAL HP is able to remove the total hydrocarbons to less than 0.05 ppm and other pollutant like Humidity, CO2, CO, NOx, SO2.

The reduction of hydrocarbons, including methane, and carbon monoxide decrease the background noise level and gives much better baseline stability, considerably increasing detector sensitivity and ensuring precise analytical results. The hydrocarbons and CO are removed with a catalytic oven filled with palladium, the Humidity and CO2 is removed with a dual molecular sieve PSA system, NO is removed with Purafil and other components are removed with an active charcoal filter.
