Parallel plate denuder for gas absorption

摘要: This invention provides a high-efficiency parallel plate wet denuder (PPWD) for gas absorption, the absorption surfaces thereof are composed of two hydrophilic porous glass plates on which TiO 2 particles coated and subsequently irradiated with UV light to form super-hydrophilic surfaces, so that it further enhances formation uniform water film increases efficiency. can be used in manual sampling devices acidic/basic gases, equipments gases gas-particle devices, besides also coupled an ion chromatograph make semi-continuous monitors.
