摘要
基于PTR-MS技术原理的基础上研发设计测试呼气中痕量挥发性有机物的系统,实现了实时在线测量.研究结果显示,系统性能良好,重复性与检验灵敏度高,响应时间短,能有效地对呼气中挥发性有机物的成分进行全谱分析.
Based on the principle of PTR-MS technology,a real-time on-line measurement system for tracing VOCs in exhaled air was developed and implemented. The results showed that the system has good performance,high repeatability and sensitivity,short response time,and can effectively perform full spectrum analysis of VOCs in exhaled air.
