摘要： 研究了横向加热石墨炉的恒温性能和分析性能,并与Massmann型炉进行了比较,结果表明,横向加热石墨炉具有较好的恒温性能,其原子化时间短、原子化温度低、原子吸收信号的占有时间短,特征质量m0值低.

关键词: 横向加热石墨炉, Massmann型炉, 恒温性能

Abstract: The isothermal and analytical performance of transversely heated graphite furnace(THGF) have been studied and discussed theoretically and experimentally, and was compared with Massmann-type graphite furnace. The results showed that THGF has better isothermal performance than Massmann-type furnace, the former has shorter atomization time, shorter occupied time of atomic absorption signal, lower atomization temperature and m 0 value.

Key words: Transversely heated graphite furnace, Massmann-type graphite furnace, Isothermal performance
