针对现行便携式Ｘ荧光仪灵敏度低、检出限差、测定元素少、基体效应校正能力弱等问题，对激发源、探测与测量系统、微机化等关键技术进行了研究。研制了微型低功率Ｘ光管激发源、低功耗１０２４道分析器，实现了以笔记本式微型计算机系统为核心的微机化，构成了高灵敏度便携式Ｘ荧光仪。它可测定多种元素，较轻和中等原子序数元素的检出限达到几至十几μｇ／ｇ，比现行便携式Ｘ荧光仪改善１个量级以上，基体效应校正和数据处理功能大为增强，携带和运输安全方便
In order to solve the problems of low sensitivity, low detection limit, low measurement element and weak matrix effect correction capability, the key technologies of excitation source, detection and measurement system and computerization are studied. Developed a miniature low-power X-ray tube excitation source, low power 1024-channel analyzer, to achieve a notebook microcomputer system as the core of the microcomputer, constitutes a high sensitivity portable X-fluorescence instrument. It can measure a variety of elements, the detection limits of light and medium atomic number elements of several to dozens of μg / g, than the current portable X-ray fluorescence detector to improve more than one order of magnitude, the matrix effect correction and data processing capabilities greatly enhanced , Carry and transport safe and convenient
