Chapter 9: Atomic Absorption Spectrometry
www2.chemistry.msu.edu• Absorption or emission of an interfering species overlaps or lies so close to the analyte absorption or emission that resolution is not possible. Rare with HCLs. • Presence of combustion products that exhibit broadband absorption or particulates that scatter radiation. Both diminish power of transmitted beam and lead to positive errors.
Flame atomic absorption spectroscopy eng - DEAC
www.chem.science.unideb.huFlame spectrometry includes three methods: a) Flame emission spectroscopy (FES): We measure the intensity of molecular bands or atomic or ionic lines emitted by excited molecules, excited atoms or even by excited ions. b) Flame atomic absorption spectroscopy (FAAS):

www1.lasalle.eduEmission vs. Absorption 3 GENLINFO.DOC, 9/10/96 1:44 PM Emission vs. Absorption All modern Perkin-Elmer atomic absorption instruments are capable of measuring both atomic absorption and atomic emission. It is important for the operator to understand the processes that occur in each technique.
