Description

一种喷射电极结构
技术领域
本发明涉及光谱仪用仪器技术领域，具体为一种喷射电极结构。
背景技术
直读光谱仪是以光电倍增管等光探测器测量谱线不同波长位置强度的装置，以色散元件将辐射源的电磁辐射分离出所需要的波长或波长区域，并在选定的波长上（或扫描某一波段）进行强度测定，在测量时，将样品固定与激发平台上，通过激发平台内的喷射电极实现激发，现有的喷射电极结构在激发过程中容易混入空气，影响激发精度。
发明内容
为了解决上述问题，本发明提供了一种喷射电极结构，其结构简单，能够保证激发精度。
其技术方案是这样的：一种喷射电极结构，其特征在于，其包括L形气流通道、喷射电极和氩气喷头，所述L形气流通道截面为圆形且包括纵向部和横向部，所述纵向部顶部开口，所述横向部侧部密封，所述喷射电极贯穿所述L形气流通道底部伸入所述纵向部，所述喷射电极与所述L形气流通道内壁之间留有气流空隙，所述氩气喷头贯穿所述横向部的侧部伸入所述横向部，所述L形气流通道顶部开口周围设置有带有倒角的环形套。
其进一步特征在于，所述喷射电极为钨电极；
所述喷射电极设置于所述L形气流通道正中间位置。
采用本发明的结构后，将需要激发的样品放置于L形气流通道上端，氩气喷头喷出氩气，顺着L形气流通道喷出，在喷射电极周围形成氩气喷射电流，喷射电极工作实现激发过程中激发点周围不会与外界空气接触，提高了激发精度，结构简单；同时钨电极延长了使用寿命，喷射电极设置于L形气流通道正中间位置保证了氩气喷射气流的均匀。
附图说明
图1为本发明结构示意图；
图2为激发状态示意图。
具体实施方式
