Chapter 10, Problem 10.3QAP
Interpretation Introduction
Interpretation:
The three emission analysis sources needs to be compared to explain the supremacy of ion lines in one and of atomic lines in the other two.
Concept introduction:
The three emission sources behave differently due to their temperature ranges and also due to the ionization of argon gas.
