摘要:
Graphite furnaces were designed to meet both the requirements of electrostatic sampling of aerosols and of delayed atomization of the sample. The metal lining of the inner surface improves the sensitivity. The carbide coating has no effect when the sample is handled as solid air particulates. High performances were obtained for the atomization of lead in different synthetic and natural matrices; better recoveries were obtained when the sample is directly atomized without chemical pretreatment.
