Hajoale, boholo ba lisebelisoa tsa ho lekanya naetrojene oxide 'marakeng li fumana hore na naetrojene dioxide (NO₂) kapa kakaretso ea nitrogen oxide (NOₓ) ke ea pele ka ho fetolela NO₂ ho kakaretso ea NOₓ (NO+NO₂) ho NO. Leha ho le joalo, ka lebaka la ts'ebetso ea phetoho ea NO₂ / NO (e itšetlehileng ka mohopolo oa sebele oa NO₂), maemo a mang a tšimo ha a tšoanelehe bakeng sa ho sebelisa converter ea nitrogen oxide bakeng sa phetoho ea NO₂-to-NO. Ho rarolla bothata bona, Shandong SINZEN Instrument Co., Ltd. e hlahisitse SUV-100 flue gas analyzer, e sebelisang mokhoa o tobileng oa ho lekanya NO₂ bakeng sa tekanyo ea litšila. Analyzer e ipapisitse le ultraviolet absorption spectroscopy le algorithms ea chemometric. E khona ho lekanya likhase tse kang SO₂, NO, NO₂, le O₂. E na le ho nepahala ha tekanyo e phahameng, ho tšepahala ho phahameng, nako ea karabelo e potlakileng, le ts'ebeliso e pharaletseng, e ka sebelisoa haholo ho lekola tikoloho ea marang-rang, taolong ea indasteri, tlhahlobo ea polokeho le lits'ebetso tse ling.

Li-analyzer tsa nitrogen oxide ke lisebelisoa tsa bohlokoa bakeng sa ho netefatsa ho lateloa ha taolo, ho beha leihlo mesi e tsoang, le ho ntlafatsa lits'ebetso tsa indasteri. Ho feta moo, ba thusa liindasteri tse fapaneng ho lekola le ho laola tlhahiso ea nitrogen oxide, kahoo ba thusa ho netefatsa hore ho latela melao ea tikoloho le ho fokotsa tšusumetso ea tikoloho ts'ebetsong ea bona. Ka ho fana ka litekanyo tse nepahetseng, tsa nako ea sebele tsa likhakanyo tsa nitrogen oxide (NOₓ), bahlahlobisisi ba NOₓ ba thusa ho kenya tšebetsong mehato e sebetsang ea taolo ea tšilafalo. Mehato ena e kenyelletsa ho lokisa lits'ebetso tsa ho tuka, ho ntlafatsa likarohano tsa mafura a moea, kapa ho kenya litsamaiso tsa "Selective Catalytic Reduction" (SCR). Ka bokhutšoanyane, lienjiniere tsa ts'ebetso li sebelisa li-analyzer tsa nitrogen oxide ho lekanya le ho sekaseka bongata ba nitrogen oxides disampole tsa khase. Bahlahlobisisi bana ba bapala karolo ea bohlokoa ho lekola tikoloho, taolo ea mosi, le ntlafatso ea ts'ebetso ho liindasteri tse fapaneng.
