Abstract: An apparatus for drawing samples of gaseous mixtures to be analyzed, such as the gaseous mixtures present at the outflow of a cracking furnace, includes a plurality of baffles arranged longitudinally inside a hollow columnar passageway so as to provide a serpentine pathway for the gaseous mixture flowing therethrough. A thermoregulator, which comprises a sleeve or jacket through which a temperature controlling fluid such as air or steam flows, surrounds the columnar passageway substantially along its length to regulate the temperature therewithin. A thermometer located at the head of the passageway, near a sampling duct through which the desired gaseous mixture is passed to an analyzer, controls the flow of fluid within the thermoregulator by sensing the temperature of the passing mixture so as to maintain this temperature at a desired value. This value is dependent on the fraction desired for analysis. Solid particles contained in a mixture are deposited on the baffles as the mixture flows through the serpentine pathway. Self-washing of these baffles is accomplished by condensation of the higher boiling fractions.
