Kev kuaj pom fluorescence yog cov tshuaj tiv thaiv luminescence ntuj, los ntawm cov tshuaj tiv thaiv ntawm luciferase thiab ATP, nws tuaj yeem ntes tib neeg lub hlwb, kab mob, pwm, thiab cov khoom noj seem, thiab tau txais cov tshuaj tiv thaiv hauv 15 vib nas this. Lub fluorescence excitation lub teeb ci yuav tsum muaj peev xwm tsim kom muaj zog txaus ntawm fluorophore kom nqus tau lub teeb nthwv dej hauv pawg. Txog tam sim no, UVA lub teeb pom kev tuaj yeem suav nrog nitrogen molecular lasers, helium-cadmium lasers, high-pressure cadmium teeb, high-pressure xenon teeb thiab hlau halide arc teeb.
UV LED fluorescence nrhiav kom tau tuaj yeem ua ke nrog lub hauv paus nruab nrab ntawm nws tus kheej. Raws li kev ncig lossis ntws ntawm qhov nruab nrab nruab nrab nkag mus rau sab nraud ntawm lub kaw lus, nws tseem nyob ntawm qhov xau, thiab cov teeb pom kev sib raug siv los txheeb xyuas sab nraud ntawm qhov system. Lub xau taw tes tso tawm cov fluorescence ci ntsa iab, yog li qhia qhov tseeb ntawm qhov xau ntawm qhov system. Fluorescent number case los tiv thaiv kev luam ntawv luam thev naus laus zis yog ib txoj hauv kev siv fluorescent number case los luam daim pib lossis cov ntaub ntawv los tiv thaiv kev dag. Hom fluorescent number case no tuaj yeem pom tib yam fluorescence nyob rau hauv ib feem ntawm cov ntawv luam tawm nyob rau hauv irradiation ntawm lub teeb liab. Tom qab cov fluorescent yog irradiated los ntawm lub teeb liab doog, lub teeb-emitting lub sij hawm luv luv thiab lub teeb ploj sai heev. Tom qab lub teeb liab doog, lub teeb ci tam sim ntawd ploj mus.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm UV LED fluorescence nrhiav pom yog tias thaum qee qhov sib xyaw ua ke nrog lub teeb ci ultraviolet, lawv tuaj yeem zoo siab los tawm fluorescence, thiab lub zog fluorescence tawm tuaj yeem suav tau los ntawm kev ntsuas lub zog fluorescence. Ntau yam tshuaj muaj feem xyuam nrog kev tshawb fawb txog lub neej, xws li amino acids, amines, vitamins, steroids, thiab qee yam tshuaj metabolic tuaj yeem kuaj pom los ntawm txoj kev fluorescence. Fluorescence detectors muaj txiaj ntsig zoo hauv kev txheeb xyuas cov kab mob lom neeg, tshwj xeeb tshaj yog tom qab siv cov tshuaj fluorescence derivatization, uas tuaj yeem ntes cov amino acids thiab peptides tsawg heev.

Qhov zoo ntawm UV LED fluorescence nrhiav kom tau:
1. High rhiab heev, UV LED fluorescence nrhiav kom tau yog cov rhiab heev cov kua chromatography detector, tshwj xeeb tshaj yog haum rau kev soj ntsuam kab.
2. Kev xaiv zoo. Cov me me ntawm cov molecules nrog cov quantum efficiency ntau txaus rau kev kuaj pom yog lub ntsiab yog vim li cas rau siab xaiv ntawm lub fluorescence detector. Hauv ntau qhov xwm txheej, qhov kev xaiv siab ntawm UV LED fluorescence nrhiav tau tuaj yeem zam kev cuam tshuam ntawm cov khoom tsis muaj fluorescent, uas dhau los ua qhov zoo ntawm kev tshawb nrhiav fluorescence.
3. Wide linear ntau. Thaum lub concentration ntawm cov tshuaj ntsuam xyuas yog loj, qhov kev siv ntawm fluorescence nrhiav pom ntawm lub emission UV LED yuav txo tau raws li qhov concentration nce vim lub internal filtering nyhuv.
4. Tsawg cuam tshuam los ntawm cov xwm txheej sab nraud.
5. Ntev npaum li qhov hnyav tau xaiv raws li lub sijhawm txawb tsis tawm fluorescence, UV LED fluorescence nrhiav tau tuaj yeem siv rau gradient elution.
