| Abstract: | Graphite electrodes heated by d.c- power alone, or a combination of d.c- and r.f. power, are investigated for generating atomic emission from cadmium with specially designed discharge lamps. Best results are achieved if the plasma produced by both power sources can be concentrated within a cylindrical electrode. |
