原子荧光光谱仪的便携化设计

Design of Portable Atomic Fluorescence Spectrometer

针对重金属污染现场快速检测领域的发展需求,成功开发首台便携式原子荧光光谱仪。实现了高度集成低功耗进样系统、微型低功耗原子化系统、数字化对光技术、微型光电检测系统以及无线通讯技术等十余项关键技术的重大突破。整机功率仅为12 W,重量仅为10kg,锂电池供电状态下工作时间不小于8h,具备与实验室常规原子荧光光谱仪相同的性能指标,可直接用于砷、汞、铅、镉等重金属的野外现场快速检测。

The first portable atomic fluorescence spectrometer was successfully developed to meet the need of in-situ and rapid detection of heavy metal elements in pollutant. Great breakthroughs of more than 10 kinds of techniques, such as high integrated-low power sampling system, miniature and low power atomization system, digital focusing technology, miniature photoelectric detecting system, wireless communication technology, etc. , were made in this instrument. The power for the spectrometer is only 12 W, the weight is 10 kg, and the running time is more than 8 hours with Lithium battery. The portable atomic fluorescence spectrometer hass the same performance as the ordinary instrument in labs, which can be directly used in for in-situ detection of arsenic, mercury, lead and cadmium, etc.
