一、引言7503C 型光电直读光谱仪是分析黑色及有色金属成份的快速定量分析仪器,这种仪器广泛应用于冶金,机械及其它工业部门,进行冶炼炉前的快速分析,以及中心实验室的成品检验,是控制产品质量的有效手段。750系列光谱仪是国内唯一生产的光电直读发射光谱仪,它具有一系列优点:(1)多通道检验方式,因此能同时进行多种元素分析,并且分析速度快捷,样品上机20秒即可得到数据完整的分析报告单。(2)结构合理,机械性能稳定,光学系统漂移量8小时不大于±5um。 I. INTRODUCTION The 7503C photoelectric direct reading spectrometer is a rapid quantitative analysis instrument for analyzing black and non-ferrous metal components. The instrument is widely used in metallurgy, machinery and other industrial sectors for rapid analysis in front of the smelting furnace and finished products in the central laboratory Inspection, is an effective means of control of product quality. 750 series spectrometer is the only photoelectric direct reading emission spectrometer in China. It has a series of advantages: (1) Multi-channel test mode, so it can analyze multiple elements at the same time, and the analysis speed is fast. The sample can be obtained in 20 seconds Complete data analysis report. (2) Reasonable structure, stable mechanical properties, optical system drift less than ± 5um for 8 hours.
