将激光剥蚀(LA)固体直接进样技术与电感耦合等离子体发射光谱法(ICP-OES)联用,并应用于中低合金钢成分分析.通过选取中低合金钢中各组分元素的分析线波长、扣除干扰背景、校正激光参数和选取基体元素Fe(274.9 nm)作为内标元素校正信号的漂移,建立了中低合金钢中Al、As、B、C、Co、Cr、Cu、Mn、Mo、Nb、Ni、P、S、Sb、Si、Sn、Ti、V、W、Zr 20种元素的LA-ICP-OES定量分析方法.研究结果表明:校准曲线的线性相关系数除硼、碳和硫外,其他元素都在0.9或0.99以上;各元素的检出限比较低,能满足中低合金钢的测定要求.方法用于测定中低合金钢标样中的上述20种元素,除个别元素在个别样品上的测定结果偏差稍大外,其他元素的测定值与认定值一致.
