A solution-cathode glow discharge (SCGD) using a novel rectangular-shaped cathode capillary is used to study aspects of the plasma-liquid interface. High-speed video of the plasma-liquid interface captured simultaneously with low-angle laser scattering from droplets near the plasma-liquid interface are studied in concert to evaluate potential mechanisms related to surface-plasma interaction. Frame-by-frame analysis of high-speed video allows estimation of droplet number density, translational speed, and rate of ejection. The data are evaluated to provide insight into potential mechanisms of analyte transport that are of importance for the use of SCGD in analytical atomic spectrometry.

溶液阴极在慢动作中的辉光放电:辉光放电灯丝结构的表征和使用矩形毛细管的液滴喷射

使用新型矩形阴极毛细管的溶液阴极辉光放电(SCGD)用于研究等离子体-液体界面的各个方面。为了研究与表面-等离子体相互作用相关的潜在机制,研究了液-液界面的高速视频并与低角度激光散射同时从液-液界面附近的液滴中捕获。高速视频的逐帧分析可以估算墨滴数密度,平移速度和喷射速率。对数据进行评估以提供对分析物传输潜在机制的深入了解,这对于在分析原子光谱法中使用SCGD至关重要。
