| 中文摘要: |
| 声表面波气相色谱仪具有灵敏度高、色谱柱升温速度快（~20℃/s）、体积小等特点，可实现痕量气体的广谱（挥发和半挥发性有机物）、快速（<5分钟）、高灵敏度（ppb～ppt级）现场分析，在公共安全、环境监测、食品和药品检测等方面有广阔的应用前景。该文从仪器响应的机理分析、检测器设计、仪器研制及应用等方面出发介绍了我们的研究进展情况。 |
| 英文摘要: |
| Surface acoustic wave gas chromatography(SAW GC) is a kind of portable gas analyzer. It has the characteristics of high sensitivity (ppb ~ ppt level) and fast heating rate of chromatographic column (~20℃/S). As a portable and fast gas analyzer, the SAW GC can achieve a broad-spectrum (Volatile and semi-volatile organic compounds), fast response (<5 min), high sensitivity (ppb ~ ppt level) for trace gases detection. And it has broad application prospects in public safety, environmental monitoring, food and drug testing. The purpose of this paper is to introduce the progress of our research of the SAW GC from the aspects of sensor response mechanism analysis, detector design, instrument development and application. |
