Qhov sib txawv tseem ceeb ntawm nplaim taws photometer thiab spectrophotometer yog tias cov nplaim hluav taws xob siv cov nplaim hluav taws xob ntsuas qhov ntsuas hluav taws xob siv qhov nqus ntawm lub teeb los ntawm cov khoom hauv cov qauv.

Ob lub nplaim taws photometer thiab spectrophotometer yog cov cuab yeej tshuaj ntsuam xyuas uas peb siv los txheeb xyuas cov qauv inorganic. Ob txoj kev no tuaj yeem ntsuas qhov concentration ntawm cov khoom xav tau hauv ib qho qauv.

Nplaim Photometer yog dab tsi?

Nplaim photometer yog ib qho kev ntsuas ntsuas uas peb siv qhov ntsuas hluav taws xob tswj. Nyob ntawd, peb siv qhov siv hluav taws xob los txiav txim siab qhov concentration ntawm cov hlau tam sim no hauv cov qauv. Yog li, peb tuaj yeem ntsuas qhov siv ntawm cov nplaim xim siv photoelectric circuitry. Qhov kev siv zog no nyob ntawm tus nqi ntawm lub zog nqus los ntawm cov atoms hauv kev tsim cov nplaim taws ntawm vaporizing lawv.

Tseem ceeb tshaj, peb yuav tsum qhia tus qauv rau cov nplaim taws ntawm tus nqi tas li. Muaj cov lim dej uas tuaj yeem xaiv cov nplaim xim. Cov lim dej no tuaj yeem tshem tawm cov kev cuam tshuam los ntawm lwm cov atoms lossis ions. Txawm li cas los xij, peb yuav tsum ntsuas lub ntsuas ntsuas ua ntej siv nws. Rau qhov calibration no, peb tuaj yeem siv cov txheej txheem kev daws teeb meem ntawm ion uas peb yuav sim. Tsis tas li ntawd, cov ntsiab lus tseem ceeb ntawm cov tshuaj uas peb tuaj yeem siv tau yooj yim siv cov cuab yeej no suav nrog sodium, potassium, lithium thiab calcium. Feem ntau ntawm cov sij hawm, pawg 1 thiab pab pawg 2 cov ntsiab lus yog qhov rhiab heev rau qhov kev sim no vim tias lawv muaj zog excitation tsawg.

Parts ntawm nplaim taws photometer:

  • Qhov chaw ntawm nplaim taws - Lub qhov cub uas tsim cov nplaim taws.
  • Nebulizer thiab sib tov chamber - thauj cov qauv mus rau nplaim taws ntawm tus nqi tas li.
  • Optical system - Ua raws li lub lim.
  • Yees duab ntes - Tshawb xyuas lub teeb tawm thiab ntsuas qhov siv ntawm cov nplaim xim.

Spectrophotometer yog dab tsi?

A spectrophotometer yog ib qho kev ntsuas ntsuas uas tuaj yeem ntsuas qhov concentration ntawm cov qauv ntawm kev ntsuas lub teeb haum. Nws siv qhov kev xav lossis kev sib kis ntawm cov khoom siv raws li kev ua haujlwm ntawm wavelength. Cov cuab yeej no tuaj yeem ua haujlwm ntawm lub teeb pom kev, nyob ze UV, thiab ze IR teeb thiab. Peb siv lub cuvette los tso cov qauv hauv qhov ntsuas. Tom qab ntawd lub teeb ci hla dhau los ntawm tus qauv thiab cuam tshuam rau hauv ib qho spectrum ntawm wavelengths thiab tom qab ntawd lub ntsuas ntsuas ntsuas qhov kev siv zog ntawm cov khoom siv sib txuas. Thaum kawg, peb tau txais cov txiaj ntsig ntawm kev tshuaj ntsuam ntawm cov khoom siv tom qab dhau lub ntsuas ntsuas.

Peb tuaj yeem siv qhov ntsuas no txhawm rau txheeb xyuas cov organic tebchaw thiab. Qhov ntawd yog los ntawm kev txiav txim siab qhov nqus qhov siab tshaj plaws. Ntxiv mus, peb tuaj yeem siv nws los txiav txim cov xim hauv ib qho spectral ntau. Qhov tseem ceeb tshaj plaws, peb siv nws los ntsuas qhov concentration ntawm cov khoom hauv ib qho piv txwv los ntawm kev txiav txim siab lub teeb absorbed los ntawm cov khoom ntawd.

Dab tsi yog qhov txawv ntawm Flame Photometer thiab Spectrophotometer?

Cov nplaim hluav taws xob yog ib qho kev ntsuas ntsuas uas peb siv cov nplaim hluav taws xob tswj. Nyob ntawd peb siv qhov ntsuas hluav taws xob tswj thiab ntsuas qhov siv ntawm cov nplaim taws ua los ntawm cov qauv thiab ntsuas qhov kev siv ntawd. Spectrophotometer, ntawm qhov tod tes, yog ib qho kev ntsuas ntsuas uas tuaj yeem ntsuas qhov concentration ntawm cov qauv ntawm kev ntsuas lub teeb haum. Ntawd yog, cov txheej txheem no siv qhov nqus ntawm lub teeb los ntawm cov khoom hauv cov qauv. Qhov no yog qhov sib txawv tseem ceeb ntawm nplaim hluav taws xob photometer thiab spectrophotometer. Tsis tas li ntawd, nplaim taws photometer ua haujlwm ntawm qhov pom ntau ntawm wavelengths thaum lub spectrophotometer ua haujlwm ntawm lub teeb pom kev, nyob ze UV, thiab ze IR teeb ntau ib yam.

Cov hauv qab no nthuav tawm cov ncauj lus kom ntxaws sib piv ntawm qhov sib txawv ntawm cov nplaim hluav taws xob thiab spectrophotometer hauv daim ntawv teev npe.

Summary – Flame Photometer vs Spectrophotometer

Ob lub nplaim taws photometer thiab spectrophotometer yog cov cuab yeej tshuaj ntsuam xyuas uas peb siv los ntsuas qhov concentration ntawm cov khoom hauv cov qauv ntawm kev kho qhov muag. Qhov sib txawv tseem ceeb ntawm nplaim taws photometer thiab spectrophotometer yog tias cov nplaim hluav taws xob siv hluav taws xob ntsuas hluav taws xob thaum lub spectrophotometer siv qhov nqus ntawm lub teeb los ntawm cov khoom hauv cov qauv.
