direct current glow discharge optical emission spectroscopy 

Initialism: DC GD-OES
https://doi.org/10.1351/goldbook.08465
Measurement method using optical emission spectroscopy in which atomization and excitation occur in a glow electric discharge sustained by a direct current electric field.
Notes:
  1. Generated argon ions impact with high energy on to the surface of the cathode, which can thus be ablated in a purely mechanical way (cathodic sputtering) or the cathode can be heated to assist evaporation (thermal volatilization).
  2. DC GD-OES is only applicable for electrically conducting samples.
