Cov txheej txheem tsim khoom niaj hnub no, los ntawm kev tshuaj xyuas cov khoom siv raw, kev tswj cov txheej txheem ntau lawm mus rau qhov kawg ntawm cov khoom zoo thiab kev soj ntsuam, yog inseparable ntawm ntau yam twj paj nruag thiab meters.Txhawm rau kom ntseeg tau tias cov khoom lag luam zoo, nws yog ib qho tsim nyog yuav tsum tsis tu ncua siv ntau yamtxheem gasestxhawm rau txheeb xyuas lossis ntsuas nws cov cuab yeej thiab ntsuas ntsuas, tshwj xeeb tshaj yog tom qab siv sijhawm ntev thiab kho cov cuab yeej online thiab ntsuas ntsuas, nws yog qhov tsim nyog yuav tsum siv cov khoom siv hluav taws xob los ntsuas qhov ntsuas.Ntau yam calibration standard gases yog raws li nram no:
| Cov khoom npe | Cov ntsiab lus | Lub hom phiaj | |
| Methane hauv huab cua | 10 × 10-6,1% | Gas chromatograph | |
| methane hauv hydrogen | 1% | ||
| Methane hauv nitrogen | 100 × 10-6,1% | ||
| Cov pa roj carbon dioxide, propane | 10 × 10-6,1% | ||
| Cov pa roj carbon monoxide hauv nitrogen | carbon monoxide | 0.5% ~ 5% | Tsheb emission analyzer |
| carbon dioxide | 0 ~ 14% | ||
| tshuaj propane | 800 × 10-6 ~ 1.2% | ||
| Sulfur hexafluoride hauv nitrogen | 0 ~ 6000 × 10-6 | Sulfur hexafluoride leak detector, sulfur hexafluoride analyzer | |
| Nitric oxide nyob rau hauv nitrogen | 0 ~ 1000 × 10-6 | Tsheb emission analyzer, chemiluminescence nitrogen oxide analyzer | |
| Oxygen hauv nitrogen | 10 × 10-6 ~ 21% | Oxygen analyzer | |
| Hydrogen sulfide hauv nitrogen | 0 ~ 20% | Hydrogen sulfide gas analyzer | |
| Isobutane hauv huab cua | 0 ~ 1.2% | Combustible gas ntsuas thiab ceeb toom ntsuas | |
| Cov pa roj carbon monoxide hauv nitrogen | 0 ~ 10% | Carbon monoxide analyzer thiab flue gas analyzer | |
| Cov pa roj carbon dioxide hauv nitrogen | 0 ~ 50% | Cov pa roj carbon dioxide analyzer, flue gas analyzer | |
| Cov pa roj carbon dioxide hauv nitrogen | 0 ~ 20% | Carbon dioxide gas tswb thiab flue gas analyzer | |
| Methane hauv huab cua | 0 ~ 10% | Optical cuam tshuam los yog methanometer, catalytic combustion methanometer | |
| Hydrogen hauv nitrogen | 0 ~ 50% | Hydrogen analyzer | |
| Ammonia hauv nitrogen | 0 ~ 30% | Ammonia analyzer | |
| Cawv hauv huab cua | 0 ~ 100 × 10-6 | Cawv tswb | |
Muaj nuj nqi ntawmtxheem gas
(1) Tsim kom muaj traceability ntawm kev ntsuas.Cov ntaub ntawv siv roj muaj qhov zoo sib xws thiab ruaj khov, tuaj yeem khaws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov ntaub ntawv, thiab hloov lawv cov txiaj ntsig hauv ntau qhov chaw thiab sijhawm.Yog li ntawd, qhov traceability ntawm kev ntsuas tuaj yeem tau txais los ntawm kev siv cov pa roj carbon monoxide rau ntau qhov kev ntsuas qhov tseeb.
(2) Txhawb kev txhim kho cov cuab yeej ntsuas thiab kev saib xyuas zoo.Cov pa roj carbon monoxide ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom zoo sib xws thiab cov txiaj ntsig kev soj ntsuam, thiab ua kom muaj kev tshawb fawb, kev tswj hwm thiab kev ncaj ncees ntawm kev saib xyuas.Hom kev txheeb xyuas cov cuab yeej tshiab, cov ntawv pov thawj metrological ntawm cov chaw soj ntsuam zoo, kuaj kev lees paub, thiab kev tsim qauv, kev txheeb xyuas thiab kev siv cov qauv hauv teb chaws thiab cov khoom lag luam roj yog sib cais los ntawm cov qauv gases.
(3) Hloov tus nqi kom muaj nuj nqis.Tus qauv rojyog ib qho txhais tau tias hloov cov nqi kom muaj nuj nqis thiab ua tiav qhov ntsuas tau zoo ib yam.Cov txiaj ntsig ntawm cov chav nyob hauv International System of Units raug xa mus rau qhov ntsuas qhov tseeb los ntawm cov qauv roj ntawm cov qib sib txawv txhawm rau kom ntseeg tau qhov tseeb ntawm qhov ntsuas ntsuas.
(4) Ua kom cov txiaj ntsig tau zoo tshaj plaws thiab zoo ib yam.Cov qauv roj tuaj yeem siv los ntsuas lossis txheeb xyuas qhov zoo ntawm cov txheej txheem ntsuas thiab ntau yam kev ntsuas, thiaj li ua kom ntseeg tau qhov sib xws ntawm kev ntsuas ntsuas hauv lub sijhawm thiab qhov chaw sib txawv.
