Abstract：The laser ablation (LA) solid direct sampling technology was combined with inductively coupled plasma optical emission spectrometry (ICP-OES), and then applied to the composition analysis of middle-low alloy steel. The analytical line wavelengths of elements in middle-low alloy steel were selected, the background interference was deducted, and the signal drifting was corrected by correcting laser parameters and selecting matrix element Fe (274.9nm) as internal standard. Consequently, the quantitative analysis method of 20 elements in middle-low alloy steel (Al, As, B, C, Co, Cr, Cu, Mn, Mo, Nb, Ni, P, S, Sb, Si, Sn, Ti, V, W and Zr) by LA-ICP-OES was established. The results showed that, except for boron, carbon and sulfur, the linear correlation coefficients of calibration curves of other elements were higher 0.9 or 0.99. The detect limits of elements were low and could meet the determination requirements of middle-low alloy steel. The proposed method was applied to the determination of 20 elements above in standard sample of middle-low alloy steel. The determination results of most elements were consistent with the certified values, and only several elements in several samples showed relatively large deviation.
