“…In our previous paper, we have reported a response performance of the power amplifier employed in the study. 10) The power supply took ca. 47.5 μs from the start of the timing pulse until the pulsed voltage has been elevated up to 50% as high as the peak voltage, 10) and thus about 100 μs was needed for loading of the full voltage.…”

This paper describes a specified measuring system for glow discharge emission spectrograph, which can provide a spatial/radial distribution of analyte atoms on the sample surface, while the conventional system provides only the information on the elemental distribution in depth direction. For this purpose, a spectrometer system consisting of an image spectrograph and an intensified charge coupled device (ICCD) detector was employed. The delay time and gate width of the ICCD detector was principally selected to improve the spatial resolution of the emitting zone. The objective of this paper was to determine an optimized set of the experimental parameter for better spatial resolution. The best spatial resolution was obtained when the gate width was 1 μs and the delay time was 60 μs. Better spatial resolution was obtained at narrower gate width, because the re-emission from the analyte atoms could be observed to a less extent when the observation was conducted more instantly just after start of the pulsed discharge.

This behavior was similar to the rising-up variation of the emission intensity, as shown in Fig.…”
