常规石墨炉原子吸收法具有灵敏度高,操作简便等优点,但常有严重的基体干扰。消除基体干扰的有效方法之一,就是实现恒温原子化。而探针原子化技术是实现恒温原子化的一种简便易行的方法。探针原子化技术是1978年由L’vov首先报导的。近年来,在探针技术的研究、探针装置自动化,以及实现多元素同时测定方面都有相当大的进展。国内对探针-石墨炉恒温原子化技术的早期工作已有介绍,但尚未见实际应用的报导。本文用自制的探针装置,在180-80型塞曼原子吸收分光光
Conventional graphite furnace atomic absorption method has the advantages of high sensitivity, easy operation, but often have serious matrix interference. One of the effective ways to eliminate matrix interference is to realize thermostatic atomization. The probe atomization technology is a simple and easy method to realize the thermostat atomization. Probe atomization was first reported by L’vov in 1978. In recent years, considerable progress has been made in the research of probe technology, the automation of probe devices, and the simultaneous determination of multiple elements. The domestic probe - graphite furnace thermostat atomization of the early work has been introduced, but no practical application of the report. In this paper, self-made probe device, 180-80 Zeeman atomic absorption spectroscopy
