Ob Chav Beam UV-Vis Spectrophotometer nrog Cov Pauv Sib Tw

Spectrophotometry yog qhov ntsuas ntawm qhov rov xav txog lossis hloov cov khoom ntawm ib yam khoom raws li kev ua haujlwm ntawm lub nthwv dej uas cuam tshuam nrog lub teeb pom, ze-ultraviolet, thiab ze-infrared.

Spectrophotometers tuaj yeem ntsuas lub teeb ci' s siv zog uas ua haujlwm ntawm nws cov xim (yoj yoj).

Cov yam ntxwv tseem ceeb ntawm spectrophotometers yog spectral bandwidth (qhov ntau ntawm cov xim nws tuaj yeem sib kis tau los ntawm cov qauv ntsuas), feem pua ​​ntawm cov qauv-kis thiab cov logarithmic ntau ntawm cov qauv-nqus.

Yog li dab tsi yog UV dual beam spectrophotometer?

UV-Vis spectrophotometer yog siv los txiav txim kev nqus ntawm lub teeb los ntawm ib qho qauv thiab tuaj yeem siv los ua tus ntsuas rau HPLC.

Ob chav nqaj spectrophotometer siv ob nqaj ntawm lub teeb: ib qho siv nqaj thiab sampling nqaj uas hla los ntawm cov qauv.

Lub hauv paus ntsiab lus ntawm UV spectrophotometer yog li cas?

Lub hauv paus ntsiab lus ntawm ultraviolet or pomabsorption

Cov tshuaj molecular uas muaj cov kab xev thiab tsis sib txuas ntawm cov khoom siv hluav taws xob (n-electrons) tuaj yeem nqus lub zog nyob rau hauv daim ntawv ofultravioletor pom lub teeb kom txaus siab rau cov hluav taws xob no ua kom muaj zog ntau dua los tiv thaiv kev sib txuas nrog molecular orbitals.
