Qhov tseem ceeb, spectroscopy yog kev kawm ntawm lub zog hluav taws xob thiab teeb meem los txiav txim siab lawv cov kev cuam tshuam, thiab nws tsis tsim cov txiaj ntsig ntawm nws tus kheej. Spectrometry yog daim ntawv thov ntawm spectroscopy kom muaj cov txiaj ntsig muaj txiaj ntsig uas tuaj yeem ntsuas tau.
Puas spectroscopy tib yam li Spectrometry?
Nyob rau hauv luv luv, spectroscopy yog theoretical science, thiab spectrometry yog kev ntsuas qhov ntsuas hauv qhov ntsuas ntawm cov teeb meem hauv atomicthiab qib molecular.
txhais li cas ntawm spectrometry thiab spectrophotometric?
GCIDE. Spectrophotometric noun. (Chem., Physics) kos duab lossis txheej txheem ntawm kev ntsuas qhov ntsuas qhov nqus ntawm lub teeb ntawm qhov sib txawv wavelengths los ntawm cov tshuaj lom neeg, los ntawm kev ntsuas spectrometer lossis spectrophotometer. Nws yog cov txheej txheem rau tshuaj ntsuam xyuas.
YPuas yog pawg spectrometry yog hom spectroscopy?
mass spectrometry, tseem hu ua huab hwm coj spectroscopy, analytic cov txheej txheem los ntawm cov tshuaj lom neeg raug txheeb xyuas los ntawm kev txheeb xyuas cov roj ions hauv hluav taws xob thiab sib nqus teb raws li lawv cov huab hwm coj-rau-them. piv. … Ob lub cuab yeej sib txawv tsuas yog nyob rau hauv txoj kev uas txheeb xyuas cov khoom raug nqi.
Vim li cas huab hwm coj spectrometry hu ua Spectrometry tsis spectroscopy?
Mass Spectrometry tsis suav nrog nthuav tawm cov molecule rau hluav taws xob. Hloov chaw nws tso siab rau cov khoom siv hluav taws xob siab (xws li cov hluav taws xob) kom them thiab tawg (sib cais) cov molecule. Cov hom raug them raug muab cais raws li lawv qhov loj rau tus nqi piv (m/z).
Pom zoo:
Tandem huab hwm coj spectrometry ua haujlwm li cas?
Nws ua haujlwm los ntawm tsim cov spectrum los ntawm kev sib cais ions ntawm qhov sib txawv ntawm qhov sib txawv rau tus nqi sib piv (m / z) qhov twg m yog molecular lossis atomic mass, z yog lub electrostatic charge unit. … Tandem huab hwm coj spectrometer yog ib qho cuab yeej siv ob (lossis ntau dua) cov ntsuas huab cua .
Vim li cas ir spectroscopy hu ua vibrational spectroscopy?
Ib lub molecule tuaj yeem co ntau txoj hauv kev, thiab txhua txoj hauv kev hu ua hom vibrational. … Unsymmetrical diatomic molecules, e.g. CO, nqus hauv IR spectrum. Ntau cov molecules complex muaj ntau daim ntawv cog lus, thiab lawv cov vibrational spectra yog sib txuas ntau dua, piv txwv li cov molecules loj muaj ntau lub ncov hauv lawv IR spectra .
Puas yog tshuaj ionization loj spectrometry?
Chemical ionization (CI) yog cov txheej txheem ionization mos siv hauv huab hwm coj spectrometry Qhov no yog thawj zaug los ntawm Burnaby Munson thiab Frank H. Field hauv xyoo 1966. … Reagent gas molecules yog ionized Los ntawm electron ionization electron ionization Electron ionization (EI, yav tas los hu ua electron impact ionization thiab electron bombardment ionization) yog ib qho ionization txoj kev uas lub zog electrons cuam tshuam nrog cov khoomlossis roj theem atoms
Puas yog huab hwm coj spectrometry rhuav tshem cov qauv?
Tom qab tag nrho, koj tau ua haujlwm hnyav los npaj tus qauv ntawd. Cov lus teb yog tsis yog, koj tus qauv raug rhuav tshem thaum lub sijhawm tshuaj ntsuam… Cov molecules hauv koj cov qauv ua ionized, nkag mus rau qhov loj spectrometer, thiab thaum kawg sib tsoo nrog cov electrodes loj analyzer.
Los ntawm txias vapor atomic absorption spectrometry?
Cold Vapor Atomic Absorption Spectroscopy lossis CVAAS yog ib qho ntawm cov txheej txheem tseem ceeb rau kev tshuaj ntsuam mercury … Qhov ntau ntawm cov tshuaj muaj nyob hauv cov qauv ib puag ncig . Dab tsi yog qhov txias vapor atomic absorption spectroscopy?
