Consider an atomic absorption spectroscopy analysis in which the target analyte is iron. Which is NOT true of the flame atomic absorbance spectroscopy of iron?
A. The iron sample is aspirated into the flame, where the solvent evaporates and the iron analyte is atomized.
B. The iron atoms in the flame absorb some of the light emitted from the hollow-cathode lamp.
C. The flame replaces the cuvet of conventional spectrometers and the flame pathlength is typically 10 cm.
D. A detector measures the amount of light generated by the flame and not absorbed by iron.
