Iolite软件具有数据处理能力强、可视化效果好和计算代码开源等优点,近年来受到国内外LA-ICP-MS实验室广泛关注。本研究探究了Iolite软件处理LA-ICP-MS元素含量信号时的应用情况,并撰写了基体归一化100%(m/m)计算代码。采用Iolite软件对仪器信号漂移校正时,发现平滑插值要优于线性插值。采用基体归一化100%(m/m)代码校准得到的BCR-2G结果显示,绝大多数元素与推荐值匹配,表明此代码是可行和可靠的。不同的外标校准物质所得的结果有差别,NIST SRM 610作外标校准物质时,BCR-2G的TiO2、MgO、K2O和稀土元素分析结果有5%~10%偏差。StHs6/80-G作外标校准物质时,Cr和Mo分析结果偏高10%~30%,这可能与基体效应或校准物质推荐值不确定度有关。合成不确定度的3个主要来源分别为校准物质测定元素推荐值不确定度、样品元素信号比值和基体归一化误差。基于Iolite软件和基体归一化100%(m/m)代码,定量校准了CGSG-1、CGSG-2、CGSG-4、CGSG-5中的50种元素,主量元素(除Mn、Ca和P外)与推荐值的偏差在5%以内,微量元素(除Cr、Ni、Zn、Ga、Mo和Sb外)与推荐值的偏差小于10%,这些数据可为CGSG标准物质实验室联合定值提供数据支撑。所撰写的基体归一化代码拓宽了Iolite软件在处理LA-ICP-MS信号时的应用范围。
