A spectrophotometer yog ib qho ntsuas ntsuas siv los ntsuas qhov sib kis lossis kev cuam tshuam ntawm pom lub teeb, UV teeb lossis lub teeb infrared …, DNA lossis RNA, kev loj hlob ntawm cov kab mob hlwb, thiab cov tshuaj tiv thaiv enzymatic.
Vim li cas peb thiaj siv spectrophotometric?
Spectrophotometry yog tus qauv thiab pheej yig cov txheej txheem los ntsuas lub teeb nqus lossis cov tshuaj lom neeg hauv cov tshuaj Nws siv lub teeb ci uas dhau los ntawm cov qauv, thiab txhua qhov sib xyaw hauv cov tshuaj absorbs los yog kis lub teeb hla ib lub wavelength.
Dab tsi yog spectrometer thiab yog vim li cas thiaj muaj txiaj ntsig?
A spectrometer yog ib lub cuab yeej rau ntsuas qhov wavelengths ntawm lub teeb hla ntau yam ntawm electromagnetic spectrumNws yog dav siv rau spectroscopic tsom xam ntawm cov khoom siv. Lub teeb pom kev tshwm sim los ntawm lub teeb ci tuaj yeem kis tau, nqus los yog cuam tshuam los ntawm tus qauv.
Lub hauv paus ntsiab lus ntawm spectrophotometer yog dab tsi?
5: Spectrophotometric. Spectrophotometry yog ib txoj hauv kev los ntsuas ntau npaum li cas cov khoom siv tshuaj absorbs lub teeb los ntawm kev ntsuas qhov siv ntawm lub teeb raws li lub teeb ntawm lub teeb dhau los ntawm cov qauv kev daws teeb meem. Lub hauv paus ntsiab lus tseem ceeb yog uas txhua qhov sib xyaw absorbs lossis xa lub teeb hla ib qho ntawm cov wavelength.
spectrophotometric siv li cas hauv lub neej tiag?
Spectrophotometry feem ntau yog siv hauv kev tshawb fawb biomedical thiab life science, uas suav nrog kev tshawb fawb thiab kev lag luam. Cov ntawv thov spectrophotometric yog ntsuas ntawm nucleic acids, proteins thiab kab mob ceev.
