question 2

Multiple Choice

In regard to atomic absorption (AA) spectrophotometry,which one of the following statements is correct?

• A) The technique combines laser-induced fluorometry and particle light scattering analysis to differentiate molecules,cells,or particles by size and shape.
• B) The technique measures concentration through the detection of absorbance of electromagnetic radiation by atoms of elements instead of molecules.
• C) Oxidation of an organic compound such as luminol induces an excited state,and light is emitted when the electron returns to the ground state.
• D) The amount of light scattered at right angles to the incident light is directly proportional to the concentration of the analyte of interest.
