Spatially-resolved observation of the excitation temperature in a glow discharge plasma for atomic emission spectrometry.
A two-dimensionally imaging spectrometer system was employed to obtain the spatial distribution of the excitation temperature in a glow discharge plasma for emission analysis. A Grimm-style glow discharge excitation source, whose hollow anode had an inner diameter of 8 mm, was observed over the whole emission area. The mapping of the excitation temperature was conducted by using a two-line meth...
متن کاملGlow Discharge Depth Profiling a Powerful Analytical Technique in Surface Engineering (TECHNICAL NOTE)
A variety of analytical techniques have been developed and employed to characterize the surfaces, subsurfaces and interfaces of surface engineering systems. They provide important information for quality control, process optimization and further development. Since the mid 1980's, glow discharge spectrometry (GDS) has emerged as an important and versatile technique for rapid depth profiling anal...
متن کاملRf glow discharge optical emission spectrometry for the analysis of arrays of Ni nanowires in nanoporous alumina and titania membranes
During the last decade, a great variety of nanostructures (nanotubes, nanofibers or nanowires) based on metals, carbons, polymers or semiconductors, have been synthesized following different synthesis procedures by using nanoporous anodic alumina membranes (AAM) as templates [1]. The principal reason for using templates of nanoporous AAM as precursor patterns lies on the possibility to obtain, ...
متن کاملSpatially-resolved observation of glow discharge plasma for atomic emission spectrometry.
An imaging spectrograph equipped with a CCD detector was employed to measure two-dimensional emission images from a glow discharge plasma in atomic emission spectrometry. The emission images at Zn I 334.50 nm for a zinc sample and at Cu I 324.75 nm for a copper sample could be obtained. Their emission intensities were not uniform in the radial direction of the plasma region but became weaker at...
متن کاملGlow Discharge Mass Spectrometry : Trace Element Determinations in Solid Samples
Glow discharge mass spectrometry (GDMS) is a mature, versatile technique for the direct determination of trace elements in a variety of materials. The technique is an extension of the earliest forms of mass spectrometry. Processes inherent to the glow discharge, namely cathodic sputtering coupled with Penning ionization, yield an ion population from which semi-quantitative results can be direct...
