Atomic absorption spectroscopy (AAS), inductively coupled plasma atomic tso pa tawm spectrometry (ICP-AES), thiab ICP-coupled mass spectroscopy (ICP-MS) yog cov kev tshuaj ntsuam feem ntau siv Kev ntsuas qis ntawm barium thiab nws cov tebchaw hauv huab cua, dej, thiab geological thiab ntau yam khoom siv lom neeg.

Ib yam li ntawd, atomic absorption spectroscopy siv rau dab tsi?

Atomic absorption spectrometry ( AAS ) yog ib qho yooj yim, high-throughput, thiab pheej yig technology siv Feem ntau los soj ntsuam cov tebchaw hauv cov tshuaj. Yog li ntawd, AAS yog siv hauv zaub mov thiab dej haus, dej, tshuaj ntsuam xyuas, thiab tshuaj.

Qhov thib ob, lub hom phiaj ntawm chopper nyob rau hauv ib qho atomic absorption spectrophotometer yog dab tsi? Piav: Lub kev ua haujlwm ntawm chopper hauv Atomic Absorption Spectroscopy yog kom tawg lub teeb ruaj khov rau hauv lub teeb pulsating. Nws yog lub log rotating muab tso rau nruab nrab ntawm cov nplaim taws thiab qhov chaw.

Ib yam li ntawd, atomic absorption spectrophotometer ua haujlwm li cas?

Atomic nqus spectrometers siv cov nqus ntawm lub teeb los ntsuas qhov concentration ntawm roj theem atoms . Ib qho hluav taws xob siab dhau ntawm cov cathode thiab anode thiab cov hlau atoms zoo siab rau kev tsim lub teeb nrog ib qho emission spectrum.

Puas yog AAS zoo lossis ntau?

Atomic absorption spectroscopy ( AAS ) yog a kom muaj nuj nqis spectro-analytical txheej txheem rau kev txiav txim siab ntawm cov ntsiab lus tshuaj siv qhov nqus ntawm qhov muag hluav taws xob los ntawm cov atoms dawb hauv lub xeev gaseous (Welz thiab Sperling, 2008).
