本文描述了一种新型手提式XRF分析仪,在矿物勘探、采矿质量管理、过程控制以及质量检查等方面的应用。本分析仪采用了一只高分辨率、工作于室温的正比计数器和一台微处理机,从而在灵敏度方面较之采用以平衡滤光片为基础的仪器有明显的改进。该仪器可以分析32种元素,每测量一次,只要通过存入计算机内供算定和校正元素间效应用的校正系数校正之后,即可完成元素含量的测定。
This article describes a new portable XRF analyzer for mineral exploration, mining quality management, process control and quality inspection. The analyzer uses a high-resolution, operating at room temperature proportional counter and a microprocessor, which in sensitivity than the use of balanced filter-based instruments have significantly improved. The instrument can analyze 32 elements, each measurement, as long as stored in the computer for calculation and calibration of the elements of the application of the correction factor correction, you can complete the determination of elemental content.
