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.
Waters Corp Sep-Pak Alumina N Plus Long Cartridge, 1710 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Plus Long cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. These versatile Plus Long cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
Waters Corp Oasis HLB Online Direct Connect Column, 80Å, 25 µm, 2.1 mm X 15 mm, 1/pk
The Oasis HLB direct connect column is designed for rugged, reproducible, and ultra-fast on-line SPE. The column contains the universal polymeric HLB sorbent, which is optimized for the extraction of a wide range of analytes from various matrices. The Oasis HLB direct connect column is intended to be used with the appropriate Waters narrow-bore analytical column, such as XSelect, XBridge, SunFire, Atlantis, XTerra, or Symmetry column. The direct connect hardware configuration provides a convenient column connection.
