AA320N Atomic Absorption Spectrophotometer
★ Ua-nyob rau hauv lub computer cov ntaub ntawv ua thiab LCD zaub: ruaj khov thiab txhim khu kev qha, nrog ib tug tuav, ncov siab, cheeb tsam, tsis siv neeg xoom hloov, deuterium teeb tom qab kho, ntau linear thiab nonlinear nkhaus haum, ntau yam tsis thiab ua hauj lwm nkhaus zaub thiab lwm yam functions.Npog thiab tshaj tawm luam ntawv, thiab lwm yam. Nws yog nruab nrog kev sib txuas sab nraud rau PC interface.
★ Kev ruaj ntseg: Lub tshuab dual-beam tuaj yeem tuaj yeem them rov qab rau lub teeb qhov chaw drift thiab wavelength drift tshwm sim los ntawm kev hloov pauv kub (nrog rau kev ua haujlwm ntawm kev tshem tawm cov nyhuv ntawm wavelength drift ntawm lub hauv paus stability) thiab hluav taws xob circuit drift, thiaj li ua tiav cov kab yooj yim stability. .
★ Ceev: Lub teeb cathode tsis tas yuav tsum tau preheated rau lub sijhawm ntev, thiab cov qauv tuaj yeem txheeb xyuas tam sim ntawd.Nws yog thawj qhov kev xaiv rau cov neeg siv los txheeb xyuas ntau lub ntsiab lus thiab tshawb xyuas cov qauv sai.
★ Kev ntsuas qhov tseeb siab: Cov pa roj system yog nruab nrog cov khoom siv hluav taws xob ruaj khov, nrog cov nplaim taws ruaj khov thiab tsis tshua muaj suab nrov.Qhov tshwj xeeb tsim cov nqaj nyias hla los ntawm cov nplaim taws kom ntseeg tau tias muaj kev soj ntsuam siab thiab kev sim thiab cov yam ntxwv tsis tshua muaj siab.
★ High-zog lub teeb txoj kev: Tag nrho cov kev xav tau yog siv los tshem tawm chromatic aberration nyob rau hauv tag nrho cov ntau yam.Los ntawm kev hloov tshuaj lom neeg, qhov chaw ncig ntawm lub teeb ci dhau los ua qhov chaw ntev thiab nkag mus rau hauv qhov slit, yog li cov flux ntawm ob lub teeb ntawm lub teeb yog txhim kho.
★ Lub neej ntev, corrosion-resistant atomization system: Lub burner txais ib yam tshiab ntawm titanium alloy cov ntaub ntawv, uas yog corrosion-resistant, ceev nyob rau hauv tshav kub tshuav nyiaj li cas, thiab muaj peev xwm ua tau raws li qhov yuav tsum tau ntsuas rhiab heev yam tsis muaj dej txias.
★ Multifunctional tsom xam qauv: cov txheej txheem rau nplaim nqus, nplaim emission, graphite rauv, atomic absorption thiab hydride tiam.
★ Kev nyab xeeb thiab txhim khu kev qha roj pa system: siv lub tshuab hluav taws xob tshwj xeeb hloov pauv ceev thiab kev tiv thaiv kev nyab xeeb, nws tuaj yeem txheeb xyuas cov nplaim hluav taws xob-acetylene thiab cov nplaim hluav taws xob nitrous oxide-acetylene, thiab tshuaj xyuas ntau dua 60 hom ntsiab lus.
★ Cov khoom siv tag nrho: muab nrog lub ntsuas, koj tuaj yeem siv tom qab yuav khoom.
