High-performance, portable ion-mobility surface-acoustic wave spectrometry

该项目旨在开发一种高性能、高性价比、掌上便携的通用化学分析差分离子迁移率光谱仪，该光谱仪工作在大气压下，功耗最低。当前分析化学中的一个重大问题是缺乏可用于现场分析许多具有环境和生物重要性的不同化学物种的快速和经济有效的方法。该项目希望能够以高选择性和高灵敏度从复杂混合物中快速和同时分离和检测许多不同的离子。该光谱仪可在野外实施各种应用，如大气监测、疾病诊断和化学武器检测。

This project aims to develop a high-performance, cost-effective, palm-portable differential ion mobility spectrometer for universal chemical analysis that operates at atmospheric pressure and consumes minimal power. A significant problem in current analytical chemistry is the lack of rapid and cost-effective methods that can be used in the field for analysis of many different chemical species of environmental and biological importance. The project expects to enable the rapid and simultaneous separation and detection of many different ions from complex mixtures with high selectivity and sensitivity. The spectrometer can be implemented in the field for various applications such as atmospheric monitoring, disease diagnosis and chemical weapons detection.
