Research Progress of Quartz-enhanced Photoacoustic Spectroscopy
摘要
石英增强光声光谱(QEPAS)技术是一种新颖的气体探测技术, 具有体积小、灵敏度高等优点, 是痕量气体检测技术的研究热点。本文对QEPAS技术的基本原理、发展历史及发展现状进行了综述, 并对多种不同结构的QEPAS系统发展情况进行了介绍, 最后对该技术的发展前景进行了展望。
Abstract
Quartz-enhanced photoacoustic spectroscopy(QEPAS) is a new technique for gas detection. It is revealed that QEPAS holds merits in many aspects, including small volume and high sensitivity. Therefore, it has become the hot researching topic of trace gas detection technique. This paper introduces the QEPAS technique principle and the structures of several different QEPAS systems. Furthermore, the development prospect of this kind technique is also predicted.
