yog tias monochromator yog (physics) ib qho khoom siv kho qhov muag, suav nrog ib lossis ntau qhov slits, uas xaiv ib pawg nqaim ntawm wavelengths los ntawm qhov dav spectrum thaum polychromator yog (physics) ib qho khoom siv kho qhov muag siv los tsim ntau lub teeb ntawm lub teeb. ntawm ntau zaus.
Tus monochromator ua dab tsi hauv spectrophotometer?
A monochromator ua lub teeb ntawm lub teeb nrog qhov nqaim heev, lossis lub teeb ntawm ib qho xim Nws yog siv rau hauv qhov ntsuas ntsuas qhov muag qhov twg lub teeb monochromatic tunable yog nrhiav. Ib tug monochromator tsim ib lub teeb ntawm lub teeb nrog ib tug nqaim bandwidth, los yog lub teeb ntawm ib tug xim.
Tus monochromator twg yog siv hauv spectrophotometer?
Qhov nrov tshaj plaws tsim rau grating monochromators hauv microplate nyeem thiab spectrophotometers yog the Czerny-Turner monochromator. Hom monochromator no siv cov iav nkhaus kom lub teeb pom kev los ntawm daim iav yog collimated tawm ntawm qhov slit (Daim duab 2).
Lub luag haujlwm ntawm monochromator yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm lub monochromator yog cais cov xim ntawm lub teeb. Nws tuaj yeem siv qhov tshwm sim ntawm qhov muag pom qhov tshwm sim hauv prism lossis hauv qhov sib txawv ntawm qhov sib txawv.
Dab tsi yog monochromator chemistry?
A monochromator yog ib qho khoom siv kho qhov muag uas xa cov kab tshwj xeeb ntawm electromagnetic spectrum Cov cuab yeej ua raws li kev sib cais ntawm qhov muaj peev xwm ntawm refraction (prism) los yog diffraction (diffraction grating). … Nws muaj cov diffraction grating (dispersing element), slits, thiab spherical mirrors.

Puas yog qhov txawv ntawm qhov hnav khaub ncaws pem hauv ntej ntawm lub qhov rais?
Tau teb koj cov lus nug, yog! Koj tuaj yeem ntxiv lub hauv siab ntawm cov tub rau khoom lossis lub txee rau pem hauv ntej ntawm lub qhov rais Lub hom phiaj yog kom nws me me, lossis qis li qhov ua tau, yog li nws cuam tshuam qhov pom tsawg li sai tau.
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm prism monochromator?
Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm prism monochromators? Nqe lus piav qhia: Qhov zoo ntawm prism yog qhov, dispersion uas tshwm sim yog tsis sib tshooj. Qhov tsis zoo yog tias nws tshwm sim hauv qhov tsis yog kab . Qhov twg hauv qab no tsis yog siv hluav taws xob emission photometer?
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
