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、掌上便携式差分离子迁移谱仪，用于在大气压下运行并消耗最低功率的通用化学分析。当前分析化学中的一个重要问题是缺乏可用于现场分析具有环境和生物重要性的许多不同化学物质的快速且具有成本效益的方法。该项目有望实现从复杂混合物中快速、同时分离和检测多种不同离子，并具有高选择性和灵敏度。光谱仪可以在现场实施，用于各种应用，例如大气监测，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.
