Double pulse laser-induced breakdown spectroscopy analysis of trace elements Cr and Mn in aluminum alloy

Key Laboratory of Optical Information Detection and Display Technology of Zhejiang, Zhejiang Normal University, Jinhua 321004, China

摘要

摘要: 采用两台波长1064 nm的调Q脉冲Nd ∶YAG激光器和多通道小型光纤光栅光谱仪，建立了一套共线双脉冲激光诱导击穿光谱分析装置。与单脉冲激光诱导技术相比，在最佳双脉冲时间延时8 μs时，Mn I 403.07 nm和Cr I 425.43 nm的光谱强度分别增加了14.3倍和17.2倍，以这两条谱线为分析线，铝合金中Mn和Cr的检测限分别由单脉冲时的73和94.5 μg/g降低至双脉冲时的3.76和4.26 μg/g，检测灵敏度提高了约20倍。

Abstract: An experimental apparatus, which consists of two identical pulsed 1064 nm Nd: YAG lasers and a portable spectrometer, has been built for element analysis in aluminum alloy in collinear dual pulse laser induced breakdown spectroscopy (DP-LIBS) configuration. 14.3- and 17.2-fold enhanced line intensities have been observed for Mn I 403.07 nm and Cr I 425.43 nm respectively, compared to that of single-pulse laser induced breakdown spectroscopy. Based on the signal intensity enhancement, inter pulse delay time has been carefully optimized, which gives a value of about 8-9 μs. Using this collinear dual pulse laser induced breakdown spectroscopy apparatus, the calibration curves for quantitative measurement of Mn and Cr were derived, and the limits of detection for elements Mn and Cr are found to be 3.76 and 4.26 μg/g, respectively.
