Abstract: A system (2) for analysis of vent gas of a urea plant (1), comprising: a Raman spectroscope (22); a sampling conduit (24) that connects the spectroscope (22) to a main pipe (20) of the urea plant (1) for conveying a sample stream (25) to be analysed to the spectroscope (22); and a temperature-adjusting device (26), operated by a temperature controller (27) and acting on at least one thermal treatment portion (28) of the conduit (24) for adjusting the temperature of the sample stream (25) circulating in the conduit (24).
