挥发性有机物模块化检测系统的研究

Research on modular detection system for volatile organic compounds

基于微流控分离技术与微机电系统加工技术,设计并制作了微型气相色谱柱。并针对工业生产中所排放的挥发性有机物进行固定相的选择与芯片涂敷。设计了一整套快速定量进样系统,并使用模块化的分离检测方式,利用不同的分离模块对不同的气体进行模块式快速分离检测。提高了检测速度,整体系统可以实现在短时间内针对多种混合气体的快速分析。

A micro gas chromatographic column is designed and fabricated based on the microfluidic separation technology and micro-electromechanical system processing technology. The stationary phase is selected according to the specific characteristics of volatile organic compounds from industrial production. A rapid and quantitative sampling system is designed,and a modular method is used to separate and detect different gases. This method greatly improves the detection speed. The fast analysis of a variety of mixed gases could be realized in a short time.
