glow discharge optical emission spectrometry (optical emission spectroscopy, emission spectroscopy, ... Processes and Techniques (hierarchy name)) |
|
Note: Optical emission spectral analysis technique in which excitation employs glow discharge, a plasma created by passing an electric current between metal electrodes in a tube containing a gas. In GD-OES a sample located in the cathode is bombarded by a glow discharge lamp. Sputtered neutral atoms excited in the plasma give off characteristic light in deexcitation which is collected by a spectrophotometer.

Additional Notes: |
|
| Dutch ..... Techniek voor de spectrale analyse van optische emissies waarin excitatie plaatsvindt door middel van glimontlading, een plasma dat ontstaat wanneer een elektrische stroom tussen metalen elektroden door een buis met gas wordt geleid. In GD-OES wordt een monster dat zich in de kathode bevindt, gebombardeerd door een glimontladingslamp. Neutrale atomen die in het plasma zijn geëxciteerd, stralen een speciaal soort licht uit als ze weer worden gedeëxciteerd. Dit licht wordt vervolgens verzameld in een spectrofotometer. |
