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.
