Atomic Absorption Spectroscopy Quiz

What does AAS stand for?

• Atomic Absorption Spectroscopy

• Analytical Absorption Spectrometry

• Automated Analysis System

• Atomic Analysis System

Which of the following elements can be detected using AAS?

• Sodium

• Iron

• Calcium

• All of the above

In AAS, the sample is first:

• Dissolved in water

• Atomized

• Filtered

• Mixed with a reagent

What is the purpose of atomization in AAS?

• To break chemical bonds and convert analyte elements into free atoms

• To increase the temperature of the sample

• To filter out impurities

• To enhance the color of the sample

What role does the monochromator play in AAS?

• It generates light

• It atomizes the sample

• It disperses light into its component wavelengths

• It detects the intensity of the transmitted light

Which of the following is NOT a part of the AAS instrumentation?

• Radiation source

• Sample holder

• Monochromator

• Gas chromatograph

The term 'excited state' refers to an atom that:

• Has lost an electron

• Is in its most stable state

• Has absorbed energy and moved to a higher energy level

• Is in the process of decaying

In flame atomization, the sample is:

• Mixed with a reagent and heated

• Sprayed into a flame where it undergoes atomization

• Dissolved in an acid solution

• Filtered and dried

What happens in the nebulization process of flame atomization?
