介绍了火花光线发射光谱仪的结构和进行熔炼光谱分析时的操作方法及样品制备方法。说明光谱仪主要由真空室、光电倍增管、火花台和计算机等部分组成;强调其测试精度取决于标准化精度和校正精度,检测人员必须严格按操作规程进行测试,光谱样品必须是用铜制敞口铸型浇注的激冷全白口试样。
The structure of the spark light emission spectrometer and the operating method and sample preparation method for the analysis of the smelting spectrum are introduced. The spectrometer mainly consists of a vacuum chamber, a photomultiplier tube, a spark stage and a computer. It emphasizes that the test accuracy depends on the standardization accuracy and the calibration accuracy. The tester must strictly follow the operating rules and the spectrometer sample must be made of copper Casting chilled all white sample.
