Photometry feem ntau yog siv rau hauv kev kawm txog cov kua thiab cov kev daws teeb meem hauv chemistry. Photometers tuaj yeem pab ntsuas cov khoom organic lossis inorganic hauv cov kua los yog kuaHauv astronomy, photometry yog siv los ntawm kev siv cov ntxaij lim dej los txwv qee qhov wavelengths thiab tso cai rau lwm qhov xav tau wavelengths los ntawm kev ntsuas.
Lub hom phiaj ntawm kev siv photometer yog dab tsi?
Photometer, ntaus ntawv ntsuas lub zog ntawm hluav taws xob hluav taws xob nyob rau hauv thaj tsam ntawm ultraviolet mus rau infrared thiab suav nrog cov spectrum pomCov khoom siv no feem ntau yog cov khoom siv hluav taws xob hloov hluav taws xob rau hauv lub tshuab. indication-piv txwv li, tus pointer txav hla lub dial.
Lub hauv paus ntsiab lus ntawm photometer yog dab tsi?
Lub hauv paus ntsiab lus ntawm cov thev naus laus zis no suav nrog ntsuas kom muaj nuj nqis ntawm lub teeb absorbing analyte hauv kev dawsQhov no tsuas yog siv tau rau cov kev daws teeb meem uas ua raws li Beer Lambert txoj cai. Cov tshuaj ntsuam xyuas uas muaj lub siab nyiam nqus lub teeb, thaum raug teeb meem ntawm lub teeb, yuav nqus tau qee qhov.
Dab tsi yog hom photometer tshaj plaws?
Photometer yog dab tsi?
- A spectrophotometer ntsuas ntau npaum li cas lub teeb pom los ntawm ib qho khoom lossis nqus los ntawm ib qho khoom.
- Qee lub yees duab siv photodiodes.
- Qee lub photometers ntsuas lub teeb nyob rau hauv photons, es tsis yog ntsuas lub teeb los ntawm lub teeb kwj.
- Digital photography yog qhov siv ntau tshaj ntawm photometers.
Puas yog photometer tib yam li lub teeb ntsuas?
Ib lub teeb ntsuas, ib hom photometer, yog siv los ntsuas tus nqi ntawm lub teeb tam sim no. Hauv kev yees duab, lub teeb ntsuas ntsuas pab tus kws yees duab txiav txim siab qhov raug kaw nrawm thiab xaiv tus lej f rau qhov xav tau.
