ABSTRACT:
An apparatus for dispersing a sample for use in combination with a pyrolysis furnace for measuring the concentration of a fluid in a process stream or environment is provided. A conduit is provided having a first end for receiving the sample and a second end through which the sample exits. The pyrolysis furnace surrounds the second end of the conduit for heating the conduit and any sample passing there through. A dispersing device is used to distribute the sample throughout the conduit such that the sample is heated in the conduit by the pyrolysis furnace without causing coking within the conduit. Also, a method for dispersing a sample for use in combination with a pyrolysis furnace for measuring the concentration of a fluid in a process stream or environment is provided. The method comprises the steps of receiving a sample into a first end of a conduit having a channel there through, passing the sample down the channel in the conduit, dispersing the sample throughout the cross section of said conduit, moving the dispersed sample down the channel in the conduit, and engaging the dispersed sample in the channel of the conduit with the pyrolysis furnace for initiating the pyrolization. Preferably, the dispersing device is quartz wool.
