Glow Discharge Mass Spectrometry

Glow discharge mass spectrometry (GDMS) is associated with two closely related techniques for the characterization of ion populations in glow discharge plasmas The materials scientist is familiar with GDMS as a tool for plasma processing diagnostics whereas the analytical chemist is familiar with GDMS as a method for direct solids analysis The present chapter will focus on GDMS as a

Atomic Spectroscopy

Atomic Spectroscopy • Atomic spectroscopy refers to measurement of elemental concentrations via optical processes of absorption emission or fluorescence as exemplified by AAS AES and AFS • Atoms change states when electrons move to different orbitals • Mass Spectroscopic techniques such as inductively coupled plasma-mass spectrometry or glow discharge-mass spectrometry are also
