Method validation of IC-ICPMS with chlorine removal for phosphite analysis (NERC Grant NE/V010824/1)

Method development for trace-level analyses of phosphite in chloride-rich matrices. Dataset includes linearity data from the ion chromatograph (IC) in stand-alone mode and coupled to the inductively-coupled plasma mass spectrometer (ICP-MS), with and without removing chloride from the solution, as well as nuclear magnetic resonance (NMR) data for phosphorus species. The results demonstrate successful removal of the chloride matrix for analyses of phosphite in solutions at sub-ppb concentrations. Additional details about the methodology are published in Baidya, A.S. and Stüeken, E.E., 2024, Rapid Communications in Mass Spectrometry, 38(1), p.e9665.

本数据集围绕高氯离子基质中亚磷酸盐的痕量分析方法开发构建，包含如下数据：离子色谱仪（ion chromatograph, IC）以单独运行模式，以及与电感耦合等离子体质谱仪（inductively-coupled plasma mass spectrometer, ICP-MS）联机联用时的线性数据，涵盖分别对溶液进行氯离子脱除与未脱除处理的两种工况；同时收录了磷形态的核磁共振（nuclear magnetic resonance, NMR）测试数据。实验结果证实，针对亚ppb级浓度溶液中的亚磷酸盐分析，可成功消除氯离子基质的干扰。本方法的详细细节已发表于Baidya, A.S.与Stüeken, E.E. 2024年刊发于《快速质谱通讯（Rapid Communications in Mass Spectrometry）》第38卷第1期、页码为e9665的研究成果中。
