UV spectrophotometer
Yog tias koj tau mus rau chav kuaj tshuaj, koj yuav tsum paub txog qhov ntsuas no. Txhawm rau txheeb xyuas hom thiab purity ntawm cov khoom, txiav txim siab qhov muaj pes tsawg leeg thiab kev ruaj ntseg tsis tu ncua ntawm cov complex, kawm cov tshuaj tiv thaiv kinetics, organic tsom xam, thiab lwm yam, qhov ntsuas no yog inseparable.
Nws yog UV spectrophotometer peb yuav qhia hnub no.

Kev kho kom raws sijhawm
Ua ntej, qhov kub thiab av noo yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm ntawm qhov ntsuas. Lawv tuaj yeem ua rau xeb ntawm cov khoom siv kho tshuab, ua rau cov hlau ua tiav ntawm cov hlau kom txo qis, ua rau muaj kev ua yuam kev lossis degradation ntawm cov khoom siv ntawm cov cuab yeej; ua rau corrosion ntawm cov khoom siv kho qhov muag xws li gratings, tsom iav, tsom iav, thiab lwm yam, ua rau lub teeb tsis txaus, lub teeb tsis pom kev, Suab nrov, thiab lwm yam, txawm tias qhov ntsuas tsis ua haujlwm, uas cuam tshuam rau lub neej ntawm lub ntsuas. Nws yuav tsum tau calibrated tsis tu ncua thaum kho. Nws yuav tsum muaj chav ntsuas nrog plaub lub caij thiab cov av noo tsis tu ncua, nruab nrog cov khoom siv ntsuas kub tsis tu ncua, tshwj xeeb tshaj yog nyob rau hauv chav kuaj nyob rau sab qab teb.
Qhov thib ob, cov plua plav thiab cov roj corrosive nyob rau hauv ib puag ncig kuj tuaj yeem cuam tshuam qhov kev hloov pauv ntawm cov tshuab tshuab, txo qhov kev ntseeg siab ntawm ntau yam kev txwv hloov, khawm, photoelectric couplers, thiab kuj ua rau ib qho ntawm cov laj thawj vim li cas aluminium zaj duab xis corrosion ntawm cov khoom yuav tsum yog. kawm. Yog li ntawd, nws yuav tsum tau ntxuav tsis tu ncua kom ntseeg tau ib puag ncig thiab ntsuas kev huv hauv tsev thiab plua plav.
3. Tom qab siv lub twj tso kua mis rau ib lub sij hawm, ib co hmoov av yuav nyob rau hauv. Nws yog qhov zoo tshaj plaws los qhib lub ntsuas ntsuas tsis tu ncua los ntawm tus kws saib xyuas kev saib xyuas lossis nyob rau hauv kev taw qhia ntawm tus kws ua haujlwm kom tshem tawm cov plua plav tawm sab hauv, thiab rov khi lub dab dej kub ntawm txhua qhov cua sov rau lub optics. Lub qhov rais kaw ntawm lub thawv raug ntxuav, txoj kev teeb pom kev zoo yog calibrated yog tias tsim nyog, cov khoom siv tau raug ntxuav thiab tsim nyog lubrication, thiab thaum kawg, lub xeev qub tau rov qab los, thiab tom qab ntawd qhov tsim nyog nrhiav pom, kho thiab kaw.
