| Abstract: | A radio frequency glow discharge(rf-GD) emission source was designed and fabricated.With this home-made rf-GD source,some basic characteristics including the stability of the plasma discharge,electric properties and spectral properties were studied for rf-GD atomic emission spectrometric analysis of conductive(materials).The discharge is stable,and the emission signal is found to be almost constant after 45 s presputtering within 9 min.Under the optimized experimental conditions,Mn and Al in BYG1916-1 standard copper(alloy) were determined and the determined values are in good agreement with the certified values.The results demonstrate that radio frequency glow discharge is a potential and useful technique for direct analysis of solid samples. |
