石墨炉原子吸收光谱仪中的原子化过程温度同步测控系统

Synchronous Measurement and Control of Atomization Temperature in Graphite Furnace

本文介绍一种根据石墨炉热辐射对原子化温度进行同步测控的系统,讨论了石墨炉发射率的影响和校准问题,同步温度信号绘制在AA—BA—温度图上,因而有利于原子吸收分析。

A sychronous system for measuring and controlling atomization temperature based on thermal radiation of graphite furnace is described. The effect of emissivity of graphite and the problem of calibration are discussed. The synchronous temperature signal in plotted on the AA-BA-Temperature diagram, that is beneficial to AA analysis.
