This invention relates a chemiluminescent gas analyzer for determining a concentration of a gaseous component (G1) in a sample gas mixture (2). The analyzer comprises a measuring chamber (3), an ozonizer (4) with ozone generating devices (44) for producing ozone-containing gas (G2), input conduits (24, 23) for delivering the ozone-containing gas and said gas mixture into the chamber and an outlet (18). A detector (7) receives radiation (E) emitted as a consequence of a reaction between the gaseous component and the ozone-containing gas. Said analyzer further comprises a flow delay device (41) in or upstream the input conduit for said ozone-containing gas and downstream from the ozone generating devices (44) of the ozonizer. The flow delay device has a delay volume (VD) causing a predetermined delay time (T) for the flow of the ozone-containing gas from said ozonizer to said measuring chamber (3).
