Spectrophotometers cuvettes feem ntau yog siv los ntsuas qhov ntau thiab zoo hauv kev tsom xam spectral. Peb txhua tus paub tias cuvettes tsis huv yuav ua rau muaj kev ua yuam kev hauv cov txiaj ntsig, tab sis ntau tus neeg tsis paub yuav xaiv cov cuvettes kom raug, nws tseem yuav cuam tshuam rau kev sim.
Yog li ntawd, thaum siv lub cuvette, muaj qee yam cuam tshuam.
Kev faib tawm ntawm cuvette:
Raws li lub wavelength ntau yam siv, nws tuaj yeem muab faib ua iav cuvettes (pom lub teeb) thiab quartz cuvettes (ultraviolet lub teeb). Cov iav cuvettes nqus yuav luag tag nrho cov ultraviolet rays, thiab absorbance loj heev. Lub absorbance ntawm quartz cuvettes yog tsawg dua. Yog li ntawd, quartz cuvettes siv nyob rau hauv cheeb tsam ultraviolet, tab sis nyob rau hauv lub teeb pom kev zoo, ob qho tib si quartz cuvettes thiab iav cuvettes yuav siv tau, thiab iav cuvettes feem ntau yog siv.
Optical txoj kev xaiv ntawm cuvettes:
Txoj kev kho qhov muag ntawm lub cuvette yog hais txog qhov kev ncua deb ntawm cov phab ntsa sab hauv ntawm lub cuvette. Feem ntau, {{0}}.5, 1, 2, 3, thiab 5 cm feem ntau siv. Txoj kev kho qhov muag yuav cuam tshuam rau lub teeb nqus tus nqi ntawm cov qauv, yog li qhov twg optical path ratio yuav tsum xaiv? Cov zaub mov xim yuav tsum tau txiav txim siab raws li qhov nqus ntawm cov qauv. Thaum cov xim ntawm cov tshuaj colorimetric yog lub teeb, xaiv ib lub cuvette nrog txoj kev kho qhov muag loj dua, xws li: 2cm, 3cm; Thaum cov xim ntawm cov tshuaj colorimetric yog tsaus dua, koj yuav tsum xaiv txoj kev kho qhov muag me me, xws li 0.5cm, 1cm Cuvette.
Yuav ua li cas qhia qhov txawv ntawm iav thiab quartz cuvettes:
Lub ntsiab txhais ntawm cheeb tsam ultraviolet yog 190-400nm, quartz cuvette tuaj yeem siv rau 190-900nm, iav cuvette tuaj yeem siv rau 360-900nm, thaj tsam ultraviolet yuav tsum siv quartz cuvette, thiab siv UV / Vis spectrophotometer, txwv tsis pub Lub wavelength qis qis tsis tuaj yeem txheeb xyuas. Raws li ib txwm muaj, nws tsis tuaj yeem paub qhov txawv ntawm quartz cuvettes thiab iav cuvettes nrog lub qhov muag, tab sis hais txog lub cev lub zog, qhov nyuaj ntawm ob yog qhov sib txawv heev, thiab qhov nyuaj ntawm quartz cuvettes yog kaum ob lub sij hawm ntau dua li cov iav cuvettes. Tsis tas li ntawd, muaj Q ntawm lub quartz cuvette (quartz quartz), thiab muaj G ntawm lub khob (iav iav), thiab ob lub cuvettes tuaj yeem ncaj qha los ntawm lo lus cim. Txawm li cas los xij, tsis yog txhua tus cuvettes muag ntawm lub khw raug cim. Nyob rau hauv cov ntaub ntawv no, lub absorbance ntawm ib tug npliag cuvette yuav kuaj tau ntawm ultraviolet wavelengths, thiab lub absorbance ntawm iav yog ntau dua li ntawm quartz.
Yuav ua li cas ntxuav cov cuvettes:
Lub hauv paus ntsiab lus ntawm kev xaiv cov tshuaj ntxuav cuvette yog tias cov nyhuv decontamination yog qhov zoo, lub cuvette yuav tsis puas, thiab kev ntsuas yuav tsis cuam tshuam rau tib lub sijhawm. Feem ntau, nws tuaj yeem ntxuav nrog dej. Yog tias nws tsis tuaj yeem ntxuav nrog dej, piv txwv li, yog tias cov tshuaj ntsuam xyuas yog cov kua qaub, siv cov tshuaj tsis muaj zog hauv qab; yog tias cov tshuaj ntsuam xyuas yog alkali, siv cov kua qaub tsis muaj zog; yog tias cov tshuaj ntsuam xyuas yog cov organic, siv cov kuab tshuaj organic, xws li cawv thiab lwm yam kev daws teeb meem.
Yog li tam sim no koj paub yuav ua li cas xaiv thiab siv lub cuvette.
