Abstract

The effect of doping gases on a reduced pressure (1 Torr) microwave-induced helium plasma has been studied. The results show that the quantity of oxygen added as a doping gas Is critical In maximizing the selectivity and sensitivity of the microwave-induced emissive spectrometric detector for the determination of chromium. The addition of approximately 3% O2 maximizes emission from atomic chromium and simultaneously quenches molecular emissions. Possible mechanisms of fragmentation and excitation are given.
