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.


LpDNPH Ozone Scrubber may be used as a sampling cartridge for the determination of volatile organic compounds in air samples using gas chromatography technique.
