YXG-14型原子吸收光谱是一台中级数字显示浓度直读式仪器。该仪器全部采用国产半导体集成元件,整个电路均采用了国内外较先进的设计方案,脉冲调制空阴灯光源,对数模拟运算电路,自动调整零点的电路,数字测量部分运用了双积分式数字电压表的设计,并在平均值数据平均化电路中采用了一种简易、合理的设计。仪器的稳定性及灵敏度均达到了设计指标。经过中期试用的结果表明,仪器的主要指标均达到国内外同类仪器的水平。
YXG-14 atomic absorption spectrometry is a mid-level digital display concentration of direct-reading instruments. The instrument uses all the domestic semiconductor integrated components, the entire circuit are used at home and abroad more advanced design, pulse modulation of the empty light source, logarithmic analog circuit, automatically adjust the zero circuit, the digital measurement part of the use of double integral number Voltmeter design, and averaging in the average data using a simple and reasonable design. Instrument stability and sensitivity have reached the design specifications. After mid-term trial results show that the main indicators of the instrument have reached the level of similar instruments at home and abroad.
