Ultraviolet thiab pom ( UV - Vis ) nqus spectroscopy yog qhov ntsuas ntawm qhov attenuation (tsis muaj zog ntawm lub zog) ntawm lub teeb ntawm lub teeb tom qab nws dhau los ntawm cov qauv lossis tom qab kev xav los ntawm cov qauv saum npoo. Kev ntsuas kev nqus tuaj yeem nyob ntawm ib lub wavelength lossis tshaj qhov txuas ntxiv spectral.

Ib yam li ntawd, koj tuaj yeem nug, UV pom spectroscopy siv rau dab tsi?

UV / Vis spectroscopy yog ib txwm siv hauv analytical chemistry rau kev txiav txim kom muaj nuj nqis ntawm cov analytes sib txawv, xws li kev hloov pauv hlau ions, cov organic sib txuas zoo heev, thiab cov macromolecules lom. Spectroscopic Kev tsom xam feem ntau yog ua tiav hauv cov kev daws teeb meem tab sis cov khoom khib nyiab thiab cov pa roj kuj tseem tuaj yeem kawm.

Tsis tas li ntawd, koj ua li cas rau UV VIS spectroscopy? Txheej txheem

  1. Tig rau ntawm UV-Vis spectrometer thiab tso cai rau lub teeb kom sov rau lub sijhawm tsim nyog (ib ncig 20 min) kom ruaj khov rau lawv.
  2. Sau ib lub cuvette nrog cov kuab tshuaj rau cov qauv thiab xyuas kom meej tias sab nraud yog huv si.
  3. Muab lub cuvette tso rau hauv lub spectrometer.
  4. Siv ib qho kev nyeem ntawv rau qhov khoob.

Kuj Paub, lub hauv paus ntsiab lus ntawm UV Visible Spectroscopy yog dab tsi?

Ultraviolet - pom spectroscopy yog suav tias yog ib qho cuab yeej tseem ceeb hauv analytical chemistry. Cov kev xav revolving nyob ib ncig ntawm lub tswvyim no hais tias lub zog los ntawm absorbed ultraviolet hluav taws xob yog qhov sib npaug ntawm lub zog sib txawv ntawm lub zog siab dua thiab lub xeev hauv av.

Dab tsi yog UV Vis spectrometer ntsuas?

UV - Saib Spectroscopy . UV - Saib Spectroscopy (los yog Spectrophotometry) yog ib qho txheej txheem ntau siv los ntsuas ntau npaum li cas cov tshuaj absorbs teeb. Qhov no yog ua los ntawm ntsuas qhov kev siv ntawm lub teeb uas dhau los ntawm ib qho qauv nrog rau kev siv ntawm lub teeb los ntawm cov qauv siv los yog qhov tsis muaj.
