Short summary
Proton-transfer-reaction mass spectrometry (PTR-MS) instruments are widely used in the atmospheric community for measuring organic trace substances in the Earth's atmosphere. Some of these substances stick onto and slowly come off surfaces in the PTR-MS analyzer, which makes it impossible to measure rapid changes in the atmosphere. Herein, we present a new type of PTR-MS instrument with a specially treated surface that mitigates this problem.
