纸喷雾质谱法已被证明可以成功分析化学战剂 (CWA) 模拟物。然而，由于模拟物和真实 G 系列（即沙林、梭曼）CWA 之间的挥发性差异，对未经处理的纸张基材进行分析非常困难。为了延长这些 G 剂的分析寿命，金属有机框架 (MOF) 被成功集成到纸喷涂基材上，以增加吸附和解吸。在这项研究中，测试了几种 MOF 和纳米颗粒，以延长纸喷雾基材上沙林、梭曼和环沙林的分析寿命。结果发现，在纸质基材中添加 UiO-66 或 HKUST-1 可将 G 试剂的分析寿命从小于 5 分钟的可检测性延长至至少 50 分钟。
Paper spray mass spectrometry has been shown to successfully analyze chemical warfare agent (CWA) simulants. However, due to the volatility differences between the simulants and real G-series (i.e., sarin, soman) CWAs, analysis from an untreated paper substrate proved difficult. To extend the analytical lifetime of these G-agents, metal-organic frameworks (MOFs) were successfully integrated onto the paper spray substrates to increase adsorption and desorption. In this study, several MOFs and nanoparticles were tested to extend the analytical lifetimes of sarin, soman, and cyclosarin on paper spray substrates. It was found that the addition of either UiO-66 or HKUST-1 to the paper substrate increased the analytical lifetime of the G-agents from less than 5 min detectability to at least 50 min.
