The AirGen series ZA TOTAL C HP is able to remove the total hydrocarbons to less than 0.05 ppm and other pollutant like Humidity, CO2, CO, NOx, SO2. ZA TOTAL C HP is available with a smart low noise built-in pistons compressor, 100% oil-free. 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.
