Attenuated tag nrho kev xav yog ib qho qauv siv los ua ke nrog infrared spectroscopy uas tso cai rau cov qauv mus kuaj ncaj qha rau hauv cov khoom lossis cov kua hauv lub xeev yam tsis muaj kev npaj ntxiv. ATR siv cov cuab yeej ntawm tag nrho cov kev xav sab hauv uas ua rau muaj evasescent nthwv dej.
txhais li cas los ntawm Attenuated Total Reflectance?
Attenuated Total Reflectance (ATR) yog tus qauv qauv uas qhia txog lub teeb rau hauv tus qauv txhawm rau kom tau txais cov ntaub ntawv tsim qauv thiab cov ntaub ntawv. … ATR yog ib txoj hauv kev los ntawm kev xav txog sab hauv, thiab tus qauv pathlength yog nyob ntawm qhov tob ntawm kev nkag mus ntawm lub zog infrared rau hauv cov qauv.
Dab tsi yog qhov Attenuated Total Reflectance ATR siv lead ua los ntawm?
Attenuated tag nrho reflectance nyob rau hauv FTIR spectrometers
Nyob ntawm daim ntawv thov thiab cov qauv ntsuas, cov ntaub ntawv sib txawv yog siv raws li ATR siv lead ua. Cov khoom siv xws li zinc selenide (ZnSe), germanium (Ge), thiab pob zeb diamond.
Qhov txawv ntawm FTIR thiab ATR yog dab tsi?
FTIR yog ib qho Fourier Transform Infrared spectroscopy txoj hauv kev ntsuas geometry, nws yuav kis tau, reflection lossis xijpeem. ATR stands rau attenuated tag nrho xav txog thiab yog tsim nyob rau hauv thiaj li yuav txhim khu lub nto rhiab heev vim IR spectroscopy yog ib tug ntau txoj kev.
Vim li cas qhov kev cuam tshuam yog attenuated ntawm ib lub kaum sab xis ntawm qhov xwm txheej?
Abib lub kaum sab xis ntawm qhov xwm txheej, yuav luag tag nrho cov teeb pom kev zoo rov qab. Qhov no tshwm sim yog hu ua tag nrho internal reflection. … Qhov kev siv ntawm lub teeb pom kev txo qis ntawm lub sijhawm no. Qhov tshwm sim no hu ua attenuated tag nrho reflectance.
