5 Questions
Interferences in AAS can only cause positive errors in quantitative analysis.
False
The main cause of background absorption in AAS is the presence of undissociated molecules of the matrix that have broad band absorption spectra.
True
Spectral interferences in AAS are caused by the presence of another atomic absorption line or a molecular absorbance band close to the spectral line of the element of interest.
True
Nonspectral interferences in AAS include chemical interference and ionization interference.
True
Spectral interferences in AAS can be overcome by choosing an alternate analytical wavelength or removing the interfering element from the sample.
True
Test your knowledge about the interferences in Atomic Absorption Spectroscopy (AAS) and their impact on quantitative analysis. Learn about the types of interferences and how they can affect the signal from the analyte in the sample.
