Kev siv cov khoom siv kho qhov muag hauv X-ray fluorescence spectrometer

Nrog txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, X-ray fluorescence spectrometry tau siv dav hauv ntau lub teb raws li txoj hauv kev zoo ntawm kev tshuaj xyuas cov khoom. Cov cuab yeej zoo tshaj plaws no tso tawm cov khoom siv nrog lub zog X-rays lossis gamma rays kom ua rau cov X-rays theem nrab, uas yog tom qab ntawd siv rau cov khoom siv hluav taws xob thiab tshuaj lom neeg. Optical Cheebtsam ua lub luag haujlwm tseem ceeb hauv cov txheej txheem no.

Lens

Lenses yog ib qho ntawm cov khoom siv kho qhov muag tseem ceeb tshaj plaws hauv X-ray fluorescence spectrometer. Lenses muaj ob qhov chaw nkhaus uas ua kom pom tseeb lossis sib txawv ntawm lub teeb, tso cai rau kev tswj hwm txoj hauv kev ntawm X-rays. Nyob rau hauv X-ray fluorescence spectrometers, lo ntsiab muag yog siv los tsom qhov kev zoo siab thib ob X-rays mus rau lub ntes kom txhim kho cov teeb liab kev ua tau zoo. Tsis tas li ntawd, qhov tseeb fabrication thiab polishing ntawm lub lens yog ib qho tseem ceeb los txo qhov tawg thiab txhim kho qhov kev daws teeb meem ntawm qhov ntsuas.

Prism

Ntxiv nrog rau lo ntsiab muag, prisms yog cov khoom siv kho qhov muag tseem ceeb hauv X-ray fluorescence spectrometers. Prisms yog ua los ntawm cov ntaub ntawv pob tshab thiab muaj peev xwm ntawm dispersing teeb pom kev zoo mus rau qhov sib txawv wavelengths. Nyob rau hauv X-ray fluorescence spectrometer, prisms yog siv los cais cov kev zoo siab thib ob X-rays los ntawm wavelength, ua rau kev txheeb xyuas thiab ntsuas cov ntsiab lus sib txawv. Kev siv cov prisms ua rau X-ray fluorescence spectrometer los tshuaj xyuas ntau lub ntsiab lus ib txhij, txhim kho kev tsom xam thiab qhov tseeb.

Tsis tas li ntawd, qee qhov tshwj xeeb kho qhov muag, xws li iav thiab cov ntxaij lim dej, yuav siv tau rau hauv X-ray fluorescence spectrometers. Reflectors yog siv los hloov kev nthuav tawm ntawm X-rays los ua kom cov twj paj nruag ntau dua; cov ntxaij lim dej yog siv los tshem tawm cov wavelengths uas tsis tsim nyog thiab txhim kho lub teeb liab-rau-suab nrov piv ntawm cov txiaj ntsig kev soj ntsuam. Kev siv cov khoom siv kho qhov muag no ntxiv txhim kho kev ua haujlwm ntawm X-ray fluorescence spectrometers.

Filter

Kev ua tau zoo thiab qhov zoo ntawm cov khoom siv kho qhov muag muaj qhov kev txiav txim siab ntawm kev ua haujlwm tag nrho ntawm X-ray fluorescence spectrometer. Yog li ntawd, kev xaiv thiab kev ua kom zoo ntawm cov khoom siv kho qhov muag yuav tsum tau txiav txim siab thaum tsim thiab tsim X-ray fluorescence spectrometers. Piv txwv li, cov ntaub ntawv tsim lub lens thiab lub vojvoog ntawm curvature yuav tsum raug xaiv los xyuas kom meej qhov kev ua kom pom tseeb ntawm cov nyhuv; thiab tus tsim ntawm prisms yuav tsum tau optimized los txhim kho wavelength daws teeb meem thiab ntsuas qhov tseeb.

Hauv kev xaus, cov khoom siv kho qhov muag ua lub luag haujlwm tseem ceeb hauv X-ray fluorescence spectrometers. Los ntawm kev tswj hwm txoj kev nthuav dav thiab kev faib tawm ntawm cov hluav taws xob xoo hluav taws xob kom raug, cov khoom siv kho qhov muag ua rau X-ray fluorescence spectrometer muaj peev xwm ua kom pom tau sai thiab raug txheeb xyuas cov tshuaj. Nrog rau kev nce qib ntawm kev siv tshuab kho qhov muag tsis tu ncua, nws ntseeg tau tias cov khoom siv kho qhov muag muaj txiaj ntsig ntau dua yuav raug siv hauv X-ray fluorescence spectrometers yav tom ntej los txhawb kev txhim kho txuas ntxiv ntawm daim teb no.
