摘要：

Glow discharge atomic spectrometry, includes principally glow discharge optical emission spectrometry (GD-OES) and GD mass spectrometry, has been widely applied in direct solid sample determination and surface depth analysis. There have been numerous methods adopted to enhance the emission signal in a GD-OES without losing the advantage of narrow spectral lines by using what is known as boosted GD sources, especially microwave discharge and magnetic field enhanced techniques. The addition of a magnetic field to the GD volume is an attractive option because it does not require much modification to the original source configuration, in addition,the presence of magnetic field lengths the drift path of electrons from plasma region to the anode,and therefore strengthens the sputtering, excitation, and ionization processes that good for signal generation.
