Fluorescence raws li yaj oxygen sensor
Txoj kev fluorescence dissolved oxygen sensor yog raws li lub hauv paus ntsiab lus ntawm fluorescence quenching. Lub teeb xiav yog irradiated rau cov tshuaj fluorescent kom ua rau nws zoo siab thiab tawm lub teeb liab. Vim cov nyhuv quenching, oxygen molecules tuaj yeem tshem tawm lub zog, yog li lub sijhawm thiab kev siv ntawm lub teeb liab zoo siab yog qhov sib piv rau qhov concentration ntawm oxygen molecules. Los ntawm kev ntsuas lub neej ntawm lub teeb liab zoo siab thiab muab piv nrog cov txiaj ntsig sab hauv, cov concentration ntawm oxygen molecules tuaj yeem xam tau.
