Nitrogen Dioxide Detection Technologies

Ntau yam thev naus laus zis muaj nyob rau kev kuaj xyuas nitrogen dioxide, suav nrog cov tshuaj tshuaj xyuas cov txheej txheem (xws li txoj kev Saltzman), electrochemical sensors, infrared spectroscopy, thiab ultraviolet fluorescence txoj kev. Ntawm cov no, electrochemical sensors tau dav siv nyob rau hauv - qhov chaw kuaj pom vim lawv cov lus teb ceev thiab txav tau yooj yim; thaum infrared spectroscopy yog qhov tsim nyog rau siab -kev kuaj xyuas qhov tseeb. Kev saib xyuas kev lag luam emission feem ntau siv cov kev soj ntsuam hauv online, uas yuav tsum ua raws li cov qauv hauv tebchaws xws li HJ 479-2009 kom ntseeg tau cov ntaub ntawv raug thiab txuas mus ntxiv.
