Atomic absorption spectrophotometric tshuaj xyuas qhov concentration ntawm cov ntsiab lus hauv cov qauv ua kua raws li lub zog nqus los ntawm qee qhov wavelengths ntawm lub teeb(feem ntau 190 txog 900 nm). … Hauv atomic absorption spectrometry, ib qho qauv yog atomized, feem ntau yog los ntawm nplaim taws lossis graphite rauv, thiab tawg mus rau hauv lub teeb.
Atomic absorption spectrophotometer yog dab tsi?
Atomic absorption spectrometry (AAS) yog ib qho yooj yim, siab-throughput, thiab pheej yig thev naus laus zis siv feem ntau los tshuaj xyuas cov ntsiab lus hauv kev daws. Xws li, AAS yog siv rau hauv cov zaub mov thiab dej haus, dej, kev tshawb fawb soj ntsuam, thiab tshuaj tshuaj.
Dab tsi tuaj yeem tshawb pom siv AAS?
Hauv kev tshuaj ntsuam xyuas, AAS tuaj yeem kuaj rau metals hauv cov ntshav, ntshav, zis, qaub ncaug, hlwb thiab nqaij nqaij, daim siab thiab plaub hau. Ib qho piv txwv uas atomic absorption spectroscopy tuaj yeem muab kev txhawb nqa tsis muaj nuj nqis yog ntsuas cov qib mercury hauv cov ntses.
Atomic absorption method yog dab tsi?
Atomic absorption spectroscopy is based on absorption of light by free metallic ions. Hauv analytical chemistry cov txheej txheem yog siv los txiav txim siab qhov concentration ntawm ib yam khoom (tus analytes) hauv ib qho piv txwv los soj ntsuam.
Dab tsi yog hom atomic absorption spectroscopy?
Muaj nplaim (F AAS), txias vapor (CV AAS), hydride-generating (HG AAS), thiab graphite rauv (GF-AAS) systems.
