Abstract
A system for on-line measurements of trace compounds in air with concentrat ions as low as a few pptv has been developed on the basis of proton transfe r reactions. The sensitivity of this system is demonstrated by means of cal ibration data of benzene and data on the diurnal variation of C9-alkylbenze ne and its C-13-isotope in ambient air. First on-line data on the concentra tions of volatile organic compounds obtained during plane flights are prese nted.
