The main factors of influencing the formation of Be and Cr(Ⅲ) acetylacetonates were investigated. It was found that the Be and {Cr(Ⅲ)} acetylacetonates were able to vaporize and introduce quantitatively into ICP with good thermal stability and volatility. The chelation reaction between the analyte and acetylacetone should be completed before the sample introduction to avoid the formation of refractory carbide and to eliminate the memory effect.展开更多
