摘要:
Proton transfer reaction mass spectrometry (PTR-MS) is a new online monitoring technique for defecting trace volatile organic compounds. It has detection sensitivity up to ppt order of magnitude in the response time of seconds. PTR-MS has wide applications in various fields such as environmental pollution monitoring, medical diagnosis and food quality inspection. In this paper, the principle and apparatus of PTR-MS are introduced. Some typical examples for its applications as well as the preliminary experimental results on the PTR-MS in author's laboratory are given. The further developments in PTR-MS are discussed.
