Xeev lub qhov zoo thiab qhov tsis zoo ntawm a rauv piv nrog kev siv a nplaim taws hauv atomic absorption spectroscopy. Lub ntsiab qhov zoo yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Qhov tsis zoo tseem ceeb yog cov cuab yeej siv ntau dua thiab cov nqi ntsuas ntsuas.
Tsis tas li ntawd, qhov zoo ntawm atomic absorption spectroscopy yog dab tsi?
Lub ntsiab qhov zoo ntawm graphite rauv (GFAAS) dhau AAS tuaj yeem sau tau raws li hauv qab no: Slurries thiab cov qauv khoom tuaj yeem txheeb xyuas ntxiv rau cov qauv hauv kev daws teeb meem. Nws qhia tau tias rhiab heev dua AAS . Yuav tsum muaj cov qauv me me (feem ntau 5-60 ΜL)
Ib yam li ntawd, graphite furnace atomic absorption spectrometry yog dab tsi? Graphite rauv atomic absorption spectroscopy (GFAAS) (tseem hu ua Electrothermal Atomic Absorption Spectroscopy (ETAAS)) yog hom spectrometry uas siv a graphite -coated rauv kom vaporize tus qauv. Kev kuaj pom txwv rau cov graphite rauv poob rau hauv ppb ntau yam rau feem ntau cov ntsiab lus.
Kuj kom paub, qhov zoo ntawm AAS tshaj Fes yog dab tsi?
Qhov zoo Atomic Absorption dhau Nplaim Photometry: (1) Nws tsis raug kev txom nyem los ntawm spectral cuam tshuam, uas tshwm sim nyob rau hauv nplaim taws emission spectroscopy. (3) Los ntawm cov txheej txheem atomic absorption, cov cim ntawm ib lub caij tuaj yeem txiav txim siab tau yooj yim nyob rau hauv muaj cov concentration ntawm lwm cov ntsiab lus.
Dab tsi yog electrothermal atomization?
Ib electrothermal atomizer yog ib yam khoom uas yog rhuab, mus rau qhov kub thiab txias uas yuav tsum tau rau analyte atomization , los ntawm txoj kev ntawm hluav taws xob tam sim no los ntawm nws lub cev.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob?
Qhov zoo tshaj plaws ntawm cov kab hluav taws xob yog tias koj tuaj yeem ntxiv cov khoom siv hluav taws xob ntxiv, feem ntau yog siv cov roj teeb. Qhov no yuav ua rau kom lub zog tag nrho ntawm koj cov zis los ntawm kev muab koj lub zog ntau dua. Koj qhov muag teev yuav tsis ci ci li thaum koj tau ua qhov no, tab sis tej zaum koj yuav tsis pom qhov txawv
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
