采用激光烧蚀-快脉冲放电等离子体光谱技术分析铝合金样品。记录了该技术激发铝合金样品后的发射光谱以及若干元素谱线的信噪比和谱线强度的相对标准偏差(RSD)。与传统的激光诱导击穿光谱技术相比,激光烧蚀-快放电等离子体光谱技术应用于铝合金样品后所产生的辐射光谱强度和信噪比均有很大提高,发射光谱线强度的相对标准偏差也得到了改善。此外还得到了采用该技术对铝合金样品中若干微量元素进行定量检测的标准曲线。 Aluminum alloy samples were analyzed by laser ablation - fast pulsed discharge plasma spectroscopy. The emission spectra and the relative standard deviations (RSDs) of signal-to-noise and spectral line intensities of several elemental spectra were recorded after the technique stimulated aluminum alloy samples. Compared with the traditional laser induced breakdown spectroscopy, laser ablation - fast discharge plasma spectroscopy applied to aluminum alloy samples produced by the radiation spectral intensity and signal to noise ratio have greatly improved, the emission line intensity relative to The standard deviation has also been improved. In addition, a standard curve for the quantitative detection of some trace elements in aluminum alloy samples has also been obtained.
