Question

Which of the following is the function of the Flame or Emission system in Atomic Absorption Spectroscopy?

• A. To split the beam into two
• B. To break the steady light into pulsating light
• C. To filter unwanted components
• D. To reduce the sample into atomic state

Hint:

In AAS, proper atomization is crucial for accurate measurement, as only atomic states of elements absorb light at characteristic wavelengths.

Answer 1

The Correct Option is D

The Flame or Emission system in Atomic Absorption Spectroscopy (AAS) serves the vital function of atomizing the sample. This process involves heating the sample to a high temperature, causing it to break apart into individual atoms. These free atoms are the ones that absorb light at specific wavelengths, which is what the AAS measures. Key Functions: - Option (D) is correct, as it directly refers to the atomization process, which is crucial for AAS. - The other options describe processes that are not the primary function of the flame or emission system in AAS.
