Iinkcukacha zeMveliso

Iithegi zeMveliso

I-F-29 uyilo olugqwesileyo lwe-optical, iphucula kakhulu ukusebenza ngokubanzi kwesixhobo;iminyaka yamava ekuveliseni izixhobo ze-fluorescent, ukuqinisekisa ukuba isixhobo sinozinzo olungcono;ngokunzulu ngakumbi ukuqonda kwabathengi, ukuya kuthi ga kwinqanaba elikhulu ngokuhambelana nemikhwa yokusetyenziswa kwabasebenzisi basekhaya.

Umgangatho ophezulu kunye nesantya esiphezulu sokuskena ukuqinisekisa ukuchaneka kwe-spectrum yovavanyo

Iimbonakalo

Uluhlu lwamaza angama-200-760nm okanye ukukhanya kwe-zero (ukhetho olulodwa lwe-photomultiplier lunokwandiswa nge-200-900nm),

Umqondiso ophezulu kwireyishiyo yengxolo 130:1 (incopho yeRaman yamanzi)

Isantya esiphezulu sokuskena isantya 3,000nm/min

Umsebenzi ophambili: ukuskena ubude be-wavelength, ukuskena ixesha

Izixhobo ezininzi ezikhethiweyo: Iisampulu zokuncamathela okuqinileyo, uncamathiselo lwePolarization, isihluzi kunye nefotomultiplier ekhethekileyo.

Imisebenzi

1.Umsebenzi wokuskena ubude bewavelength ikakhulu ubandakanya iindlela ezimbini zedatha: intensity fluorescence kunye nokukhanya okukhanyayo.I-excitation spectrum kunye ne-fluorescence spectrum yeesampuli inokufumaneka ngemodeli yedatha ye-fluorescence intensity, eyindlela eqhelekileyo.
2.Ixesha lokuskena ixesha lokuskena kukuqokelela ijiko le-fluorescence intensity curve yesampula evavanyiweyo kunye nexesha phakathi kwexesha elichaziweyo.Ingasetyenziselwa ukubeka esweni utshintsho lwe-physicochemical yesampuli, kwaye indlela yekinetic inokuqhutywa.
I-3.Indlela ye-Photometric isebenzisa indlela ye-wavelength yokulinganisa ubungakanani, ukuya kuthi ga kwi-20 iisampulu eziqhelekileyo zinokulinganiswa, i-polygonal standard curve inokuzotywa kwindawo nganye yoxinaniso oluqhelekileyo, ukulungiswa kwe-regression standard curve kunokusebenzisa i-curve yokuqala, yesibini, yesithathu yamandla okanye umgca ophukileyo, kunye ne-coefficient yokulungelelanisa i-R kunye ne-R2 inokufumaneka ngexesha elifanayo.
4. Umsebenzi onamandla wokucubungula i-spectrum, ii-spectrum ezimbini zinokuthi zongezwa, zikhutshwe, ziphindaphindwe kwaye zihlulwe, kwaye zingabala ummandla we-spectrum;ngolungiso lwe-spectrum kunye nolawulo lwe-shutter, njl.
