UV1910 / UV1920 Ob Chav Beam UV-Vis Spectrophotometer
Nta
Spectral bandwidth:Lub spectral bandwidth ntawm lub ntsuas yog 1nm / 2nm, uas ua kom ntseeg tau zoo heev spectral daws teeb meem thiab raug yuav tsum tau rau kev tsom xam.
Ultra-low stray teeb:zoo heev CT monochromator optical system, advanced hluav taws xob system, kom ntseeg tau tias ultra-low stray teeb theem zoo dua 0.03%, kom tau raws li tus neeg siv qhov kev xav tau ntawm cov qauv absorbance siab.
Cov khoom siv zoo:Cov khoom siv tseem ceeb yog ua los ntawm cov khoom lag luam zoo tshaj plaws los xyuas kom muaj kev ruaj ntseg thiab lub neej ntev ntawm cov cuab yeej. Piv txwv li, cov khoom siv lub teeb ci tseem ceeb yog muab los ntawm lub neej ntev deuterium teeb ntawm Hamamatsu hauv Nyij Pooj, uas lav lub neej ua haujlwm ntawm ntau tshaj 2000 teev, txo qhov kev saib xyuas ntau zaus thiab tus nqi ntawm txhua hnub hloov lub teeb ntawm qhov ntsuas.
Long-term stability thiab kev cia siab rau:Tus tsim ntawm lub optical dual-beam optical system, ua ke nrog real-time digital proportional tawm tswv yim teeb liab ua, zoo offsets lub teeb liab drift ntawm lub teeb qhov chaw thiab lwm yam khoom siv, kom lub sij hawm ntev stability ntawm lub ntsuas ntsuas.
High wavelength raug:Lub high-theem wavelength scanning mechanical system ua kom qhov tseeb ntawm wavelengths zoo dua 0.3nm thiab rov ua dua ntawm wavelengths zoo dua 0.1nm. Cov cuab yeej siv lub teeb tsa hauv spectral cov yam ntxwv wavelengths los ua qhov kev tshawb nrhiav wavelength thiab kho kom ntseeg tau tias lub sijhawm ntev wavelength raug ruaj khov.
Lub teeb qhov chaw hloov yog yooj yim:qhov ntsuas tuaj yeem hloov pauv yam tsis tau tshem lub plhaub. Lub teeb qhov chaw hloov daim iav txhawb kev ua haujlwm ntawm kev nrhiav qhov zoo tshaj plaws. Lub hauv-kab deuterium tungsten teeb tsim tsis tas yuav kho qhov muag debugging thaum hloov lub teeb ci.
Ntsuasyog nplua nuj nyob rau hauv functions:Covntsuasyog nruab nrog 7-nti loj-screen xim kov LCD npo, uas tuaj yeem ua lub sijhawm ntsuas lub sijhawm, tshawb xyuas ntau lub wavelength, tsom xam ntau, thiab lwm yam, thiab txhawb kev khaws cov txheej txheem thiab cov ntaub ntawv. Saib thiab luam daim ntawv qhia. Yooj yim rau siv, yoog raws thiab ua haujlwm zoo.
Muaj hwj chimPCsoftware:qhov ntsuas tau txuas nrog lub computer ntawm USB. Cov software hauv online txhawb nqa ntau yam haujlwm xws li kev soj ntsuam wavelength, tshawb xyuas lub sijhawm, ntsuas kev ntsuas, ntsuas ntsuas ntau, ntsuas ntau lub wavelength, DNA / RNA tsom xam, ntsuas ntsuas ntsuas, thiab ntsuas kev ua haujlwm. Txhawb cov neeg siv txoj cai tswj hwm, kev ua haujlwm traceability, thiab ua tau raws li ntau yam kev xav tau hauv ntau qhov kev tshuaj xyuas xws li cov tuam txhab tshuaj.
