摘要

本文采用激光诱导击穿光谱法（LIBS）和激光烧蚀电感耦合等离子体质谱法（LA-ICPMS）来评价烧结和样品密度对测量结果的影响。在不同温度下煅烧制备了两组质量密度不同的氧化锆球团。本研究的新颖之处在于确定了两种独立技术（LIBS和LA-ICPMS）的U-Zr氧化物颗粒密度对激光采样的影响。详细讨论了样品密度对优劣系数的影响。在还原气氛（Ar/H2）下的高温烧结增加了颗粒密度，提高了信号强度、相关系数（R2）、检测限、精度和LIBS的准确性。用1064 nm Nd:YAG激光对LA-ICPMS结果也有类似的影响，而用193 nm ArF准分子激光对LA-ICPMS结果的影响可以忽略。

Effect of oxide pellet density on laser sampling for LIBS and LA-ICPMS

Laser-induced breakdown spectroscopy (LIBS) and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) are employed in this article to evaluate the effect of sintering and sample density on the measurements. Two sets of U-Zr oxide pellets of different mass densities are prepared by calcination at two different temperatures. The novelty of the present study is to determine the effect of U-Zr oxide pellet density on laser sampling for two independent techniques (LIBS and LA-ICPMS). The impact of sample density on figure-of-merits is discussed in detail. Sintering at higher temperatures in a reducing atmosphere (Ar/H₂) increases pellet density and improves signal intensity, correlation coefficient (R²), detection limit, precision, and accuracy for LIBS. A similar effect of pellet density is observed for LA-ICPMS result with 1064 nm Nd:YAG laser, whereas there is a negligible effect with 193 nm ArF excimer laser.
