| Research Abstract |
This study spectroscopically analyzed a minute-volume liquid solution using glow corona with a size of a few micro-meters. Glow corona, a type of microplasma, had never been applied to chemical analyses. The solution was transported to the tip of a microcapillary electrode through the inside, and reacted with the glow corona generated at the tip. The effects of the voltage modes and the electrode diameter on the behavior of the solution surface in the glow corona were quantitatively investigated, which leaded to determining an optimal discharge condition where noelectrospray occurred. Two compact test chambers were developed, and the emission spectra of the components of solutions were obtained.
