Question
  1. Consider the analysis of a sample of iron using atomic absorbance spectroscopy. Which of the following statements are true? Select all that apply.

     

    The iron sample is aspirated into the flame, where the solvent evaporates and the iron analyte is atomized.

    The hollow-cathode lamp for iron emits wavelengths of light unique for iron.

    A detector measures the amount of light generated by the flame and not absorbed by iron.

    The iron atoms in the flame absorb some of the light emitted from the hollow-cathode lamp.

    The flame replaces the cuvet of conventional spectrometers and the flame pathlength is typically 10 cm.
