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
