PTR-QMS 3500 Proton transfer reaction mass spectrometry
Product Introduction
Proton transfer reaction mass spectrometry (PTR-MS) is an analysis instrument used to separate and detect the protonated charged particles by the quality analyzer at the next stage, which are formed by the proton transfer reaction between the component to be tested and the reagent ion under specific conditions. This instrument is mainly used for the detection of volatile organic compounds (VOCs). It can be used for real-time online continuous monitoring and continuous quantitative measurement of volatile organic compounds such as benzene series, most alkanes, alkenes, ethers, lipids, etc.
