Emission spectroscopic analysis using micro-glow corona

本研究使用几微米大小的辉光电晕光谱分析一种微量液体溶液。辉光电晕是一种微等离子体，以前从未应用于化学分析。该溶液通过内部传输到微毛细管电极的尖端，并与尖端处产生的辉光电晕反应。定量地研究了电压模式和电极直径对辉光电晕中溶液表面行为的影响，从而确定了无电喷雾发生的最佳放电条件。研制了两个小型试验箱，获得了溶液组分的发射光谱。

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.
