In this work, we compared results from two methods for the determination of Ar(1sy) densities in an Ar-N2 discharge. Both methods involve measurements of Optical Emission Spectroscopy (OES).The first method (bands method), uses the bands corresponding to Second Positive System (SPS) of N2, while the second method (line intensities ratio method), uses the line intensities corresponding to transitions Ar(2px -> 1sy). These techniques were tested in the negative glow and the results show good agreement
