Waters Corp Sep-Pak Ozone Scrubber Potassium Iodide, Plus Short Cartridge, 1.4 g, 55 - 105 µm , 20/pk
Ozone has been shown to interfere with the analysis of carbonyl compounds in air samples that have been drawn through cartridges containing silica-coated with2,4-dinitrophenylhydrazine (DNPH). Waters Ozone Scrubber cartridges are designed to remove this ozone interference. These disposable devices are intended for use in series combination with the Waters Sep-Pak DNPH-Silica cartridges or XPoSure. Aldehyde Sampler cartridges. One Ozone Scrubber cartridge replaces the 1.4in. diameter by 36in. long copper ozone denuder located in the heated zone of sampling systems used for outdoor air monitoring (PAMS program). Each Ozone Scrubber cartridge contains 1.4 grams of granular potassium iodide. When air containing ozone is drawn through this packed bed, iodide is oxidized to iodine, consuming the ozone.
