Abstract
Abstract The invention relates to an apparatus for measuring chemical and/or physical reaction sequences by nuclear magnetic resonance spectrometry and comprises a reaction path (1), a nuclear magnetic resonance spectrometer (2) and at least one reaction chamber (10) which is located in the reaction path, wherein means are provided for feeding at least the reaction product from the reaction chamber (10) to the nuclear magnetic resonance spectrometer (2). According to the invention, at least reaction chamber (10) and its reagent supply and discharge lines (5 to 7) are mounted, by means of a mounting angle (29), on the same head housing (9) on the latter's end which projects from the spectrometer magnet bore, in the stray field of the spectrometer magnet.
