克服一米光栅摄谱仪水平电极撒料装置污染问题

Resolving the contamination problem of spreading device of horizontal electrode for one-meter grating spectrograph

水平电极撒料电极架同平面光栅摄谱仪主机配合使用，可降低光谱分析成本，减少分析人员劳动强度，提高工作效率，缩短分析项目周期。检出限为1×10^-9（g·g^-1）～1×10^-6（g·g^-1），可检测24个元素，能满足化探扫描的需要。

horizontal pole spreader is used together with plane grating spectrograph, which can reduce analyst cost and labor in- tensity, improve work efficiency and shorten analyzing cycle. Its measurement scope is from 1×10^-9 （g·g^-1 ） to 1 ×10^-6 （g·g^-1 ）, 24 elements will be detected, and can meet the requirement of scanning analysis.
