摘要

Process for measuring ethylene comprises subjecting a measuring gas containing ethylene and ozone in excess to a homogeneous gas phase reaction in a reaction chamber. A chemiluminescent beam is produced by the gas phase reaction and is measured by a photomultiplier. The measured beam is a measure for the ethylene content in the measuring gas. An Independent claim is also included for a device for measuring ethylene comprising a reaction chamber having inlet openings for ozone in excess and a measuring gas containing ethylene and an outlet opening for a waste gas stream.
