本文介绍在光电直读光谱测定纯铝中铁、硅、铜时,应用HFI—1型高压火花脉冲发生器,提高分析精密度和速度。激发与记录光谱的条件使用带WGD-731型光电直读装置的(?)-30型石英光谱仪,三透镜照明系统。入射和出射狭缝均为30微米;极距2.5毫米;水平电极架;φ7毫米铝棒试样,车成平面,双样品对极;预然3秒;自动曝光法控制曝光时间(电平5,约7秒);光源HFI-1型高压火花脉冲发生器。参数选择采用多因素正交试验法选择最佳条件
This article describes the use of HFI-1 high-voltage spark pulse generator for the determination of iron, silicon and copper in pure aluminum for direct reading spectroscopy to improve the precision and speed of analysis. Conditions for Excitation and Recording Spectroscopy A (?) - 30 quartz spectrometer with a WGD-731 photoelectric direct reading device, a three-lens illumination system was used. The incidence and exit of the slit are 30 microns; polar distance 2.5 mm; horizontal electrode frame; φ7 mm aluminum rod sample, the car into a plane, the two samples on the pole; the default 3 seconds; exposure time automatic exposure control (level 5 , About 7 seconds); light source HFI-1 high-voltage spark pulse generator. Parameter selection using multi-factor orthogonal test method to select the best conditions
