Question 1 of 15

What is the basic principle behind Inductively Coupled Plasma Spectroscopy (ICP-OES)?

  1. Atoms in a sample are excited to high energy levels and emit light when they return to their ground state.
  2. Atoms in a sample are ionized and the resulting ions emit light.
  3. Atoms in a sample are heated to a high temperature and emit light.
  4. Atoms in a sample are subjected to a magnetic field and emit light.
