中文摘要
设计、制造并评价了一种廉价的便携式钨圈原子吸收光谱仪。该装置将由可靠的钨丝线圈雾化器、安装在PC卡上的微型光谱仪/检测器组合和近线背景校正方法组成。该仪器将由一个普通的12伏汽车电池供电,通过汽车点烟器连接,并由笔记本电脑控制。检测环境中的有毒化学物质是极其重要的。所提出的设备将吸引各种各样的实验室,致力于检测这些化学物质,并定期进行微量金属测定。
英文摘要
9523190 Brown An inexpensive, portable tungsten coil atomic absorption spectrometer will be designed, constructed, and evaluated. This device will be a combination of a reliable tungsten coil atomizer, a miniature spectrometer/detector combination mounted on a PC card, and a near-line background correction method. The instrument will be powered by a normal 12 volt car battery connected through a car's cigarette lighter, and controlled with a laptop computer. The detection of toxic chemicals in the environment is extremely important. The proposed device will be attractive to a wide variety of laboratories that are dedicated to the detection of these chemicals and perform trace metal determinations regularly.
