Condensate removal apparatus for sampling

An auxiliary heat exchange system for use in gas sampling, the system comprising:

• a first conduit and a second conduit both housed in an external casing, wherein each of the first conduit and the second conduit first conduit are removably attachable to a heat/cooling system of a vehicle;
• a tracer conduit, having a first length, for transporting gas samples, wherein the tracer conduit is positioned proximate to the first conduit and the second conduit and housed in the external casing for at least a partial length of the first conduit and the second conduit, wherein the tracer conduit comprises a first end removably attached to a gas collection device and a second end removably attachable to a measuring device;
• and
• wherein the first conduit and the second conduit are configured to carry heated liquid from the heating/cooling system of the vehicle to maintain at least a threshold temperature of the gas samples in at least a majority of the length of the tracer conduit to reduce the formation of condensates in the tracer conduit.
