What is the basic principle behind Inductively Coupled Plasma Spectroscopy (ICP-OES)?
AnswerClick to flip back
A
Atoms in a sample are excited to high energy levels and emit light when they return to their ground state.
💡 Explanation:
In ICP-OES, the sample is introduced into an inductively coupled plasma (ICP), which is a high-temperature, ionized gas. The atoms in the sample are excited to high energy levels by collisions with the ions in the plasma. When these atoms return to their ground state, they emit light at specific wavelengths that are characteristic of the element.
