矿用半导体探测器金分析仪的出现,是八十年代手提式放射性同位素x射线荧光分析仪(简称PIF仪)的一个重大发展。在矿山的勘探和开采过程中,为了提高采掘效率、减少矿石的贫化损失,就地进行矿石多元素快速分析,已提到日程上了。然而常用的矿用PIF仪是采用能量分辨率较低的闪烁探测器或正比计数器做成探头,一般只能进行单元素测量,其灵敏度也受到很大限制。
The emergence of mining semiconductor detector gold analyzer, eighties is a portable radioisotope x-ray fluorescence analyzer (PIF instrument for short) a major development. In the process of exploration and exploitation of mines, in order to improve the efficiency of extractive mining and reduce the depletion loss of ore, a rapid on-site multi-element analysis of ore has been put on the agenda. However, the commonly used mine PIF instrument uses a scintillation detector or proportional counter with a lower energy resolution to make a probe. Generally, only a single element measurement is performed, and its sensitivity is also greatly limited.
