1. Principle
GDOS makes analytical use of the phenomena that take place in a discharge source. We will describe the macroscopic operation of a schematic discharge tube, before detailing the microscopic processes of ionization and light excitation of the particles present in the particular sources used in optical emission spectrometry, operating in an "abnormal" discharge regime.
1.1 Characteristics of a discharge tube
If a direct current is applied to the two flat, parallel electrodes of the cylindrical tube containing a low-pressure gas (usually a few hundred pascals) shown in figure 1 , the current-voltage characteristic obtained has the appearance shown in figure...
