Application

LpDNPH Ozone Scrubber was used to remove ozone, in an experiment conducted to develop emission factors for air pollutants, after burning sugarcane, using combustion chamber method. It was also used to chemically remove ozone and reduce the decomposition, in an experiment conducted to study different active sampling procedures and analysis of aldehydes done at environment level.

General description

Ozone scrubbers are recommended for sampling carbonyls in high humidity environments. These cartridges contain 1.5 g of high purity potassium iodide (KI) and are available in two cartridge styles. KI traps the ozone which causes a negative formaldehyde interference in DNPH coated devices. The reversible cartridge offers a slip luer end-fitting, and the rezorian cartridge offers a luer lock end-fitting, to enable you to connect your cartridge of choice directly to the inlet of any DNPH cartridge with a like end-fitting. Testing (200 ppb ozone, 50 % RH, 25°C) indicates the ozone scrubber to have an ozone capacity of 100,000 ppb/hr.
