Izinzwa zomoya-mpilo zisetshenziselwa ukulinganisa nokuqapha amazinga okugxiliswa komoyampilo, umoya-mpilo ohogelwe futhi ukhishwe isiguli esixhunywe kumshini wokuphefumula noma wokubulala izinzwa.
Inzwa ye-oksijini kusiqaphi segesi yokuphefumula (i-RGM) ikala ukugxiliswa komoyampilo (noma) ukucindezela kwengxenye ye-oxygen kungxube yegesi yokuphefumula.
Izinzwa zomoya-mpilo zaziwa nangokuthi izinzwa ze-FiO2 noma amabhethri e-O2, futhi ingxenyenamba ye-oxygen ehogeliwe (FiO2) iwukugcwala komoyampilo kungxube yegesi.Ingxenye ye-oksijini ephefumulelwe yengxube yegesi emoyeni wegumbi lomoya ingama-21%, okusho ukuthi ukugcwala komoyampilo emoyeni wegumbi kungu-21%.
Kungani ama-RGM edinga inzwa ye-oxygen?
Konke ukuqapha kwegesi ephefumulayo kuklanyelwe ukuhambisa ingxube yomoya nomoya-mpilo ingene futhi iphume emaphashini esiguli ukuze kusize ngokuphefumula, noma kwezinye izimo, ukuze kuhlinzekwe ukuphefumula kwemishini esigulini esiphefumula ngokwanele noma esingakwazi ukuphefumula umzimba.
Ngesikhathi sokuphefumula, ukukala okunembile kwengxube yegesi yokuphefumula kuyadingeka.Ikakhulukazi, ukukala umoya-mpilo ngesikhathi sokuphefumula kubalulekile ngenxa yokubaluleka kwawo kumetabolism.Kulokhu, inzwa ye-oxygen isetshenziselwa ukulawula nokubona ukunikezwa komoya-mpilo okubaliwe kwesiguli.Imfuneko eyinhloko ukunikeza ukunemba okuphezulu kokuqukethwe komoyampilo kumagesi okuphefumula.Izindlela Ezihlukene Zezinzwa Ze-Oxygen Yezokwelapha
Izinzwa ze-Electrochemical
Inzwa ye-oxygen ye-Fluorescent
1. Electrochemical oxygen sensor
Izakhi zokuzwa komoya-mpilo we-Electrochemical zisetshenziswa kakhulu ukukala okuqukethwe komoyampilo emoyeni osemoyeni.Lezi zinzwa zihlanganiswe emshinini we-RGM ukukala ukugxila kokunikezwa komoya-mpilo.Zishiya izinguquko zamakhemikhali kusici sokuzwa, okuholela ekuphumeni kukagesi ngokulingana nezinga le-oxygen.Izinzwa ze-Electrochemical ziguqula amandla amakhemikhali abe amandla kagesi ngokusebenzisa i-oxidation nezinqubo zokunciphisa.Ihlinzeka ngokukhipha ugesi kudivayisi ngokulingana nephesenti le-oxygen ku-cathode ne-anode.Inzwa ye-oxygen isebenza njengomthombo wamanje, ngakho-ke ukulinganiswa kwe-voltage kwenziwa nge-resistor yomthwalo.Umphumela wamanje wenzwa yomoya-mpilo ulingana nezinga lokusetshenziswa komoya-mpilo yinzwa ye-oxygen.
2. Inzwa ye-oxygen ye-Fluorescent
Izinzwa ze-Optical oxygen zisekelwe kumgomo we-fluorescence quenching of oxygen.Bathembele ekusetshenzisweni kwemithombo yokukhanya, izitholi zokukhanya nezinto ezikhanyayo ezisabela ekukhanyeni.Izinzwa ze-oxygen ezisekelwe ku-luminescence zithatha indawo yezinzwa ze-electrochemical oxygen emikhakheni eminingi.
Umgomo wokucisha i-oxygen fluorescence yamangqamuzana kade yaziwa.Amanye ama-molecule noma ama-compounds fluoresce (okungukuthi, akhipha amandla okukhanya) lapho evezwe ekukhanyeni.Kodwa-ke, uma ama-molecule e-oksijini ekhona, amandla okukhanya adluliselwa kuma-molecule e-oksijini, okuholela ekunciphiseni kwe-fluorescence.Ngokusebenzisa umthombo wokukhanya owaziwayo, amandla okukhanya atholiwe alingana ngokuphambene nenani lama-molecule komoyampilo kusampula.Ngakho-ke, lapho kutholwa i-fluorescence encane, kufanele kube khona ama-molecule e-oksijini engeziwe kusampula yegesi.
