Which component destroys any analyte ions and breakdown complexes to create atoms (the elemental form) of the element of interest?

• A. Light
• B. Flame
• C. Monochromator
• D. Detector

Answer: (B)

Atomization is what’s being tested—the ability to turn the analyte from a compound into free atoms so they can be measured. The flame provides the high temperature needed to break chemical bonds and dissociate complexes, and it can also reduce ions to neutral atoms of the element of interest. With these atoms in the gas phase, they can be excited or interact with light to produce a measurable signal.

The other components don’t perform atomization. Light serves as the energy source to excite atoms or to provide the spectral lines for emission or absorption, not to break bonds. The monochromator selects light at a specific wavelength after the signal is produced, filtering it for measurement. The detector converts the light signal into an electrical signal, but it does not atomize the sample.
