Laser ablation for aerosol deposition graphite furnace atomic absorption spectrometry

摘要: Abstract A commercially available pulse laser was used with a graphite furnace (GF) atomic absorption (AA) spectrometer for the trace analysis of metals in solid samples. Laser ablated material deposited onto inner surface GF. The optimum deposition temperature 300 K. aerosol atomized conventional GF heating regime. analytical results technique Cd, Zn, Pb, Ag, Mn, Fe and Ni contained different target materials were compared obtained another ablation technique, which is characterized by transport into constant immediate atomization particles. improved sensitivity precision low volatile elements Zn Pb. In contrast, injection preferable determination that require more energy atomization. Working tube temperatures up to 2800 K authors higher absorbance values (peak height) using technique. use multiple inside achieve detection limits one seems promising only selected matrices.
