1. A vapor generator mixing chamber apparatus comprising:
a. an inlet manifold defining a tubing manifold port and a plurality of vapor ports;
b. an outlet manifold defining one or more sample ports and an exhaust port;
c. a mixing chamber having a first end defined by the inlet manifold, a second end defined by the outlet manifold, and one or more chamber walls extending between the inlet and outlet manifolds;
d. a tubing manifold extending from the tubing manifold port of the inlet manifold at least partially into the mixing chamber,
the tubing manifold comprising an elongate body having an open end, an opposing closed end, and inner and outer longitudinal surfaces, the inner longitudinal surface defining a duct extending from the open end to the closed end, wherein the elongate body defines a plurality of holes extending through the inner and outer longitudinal surfaces into fluid communication with the duct;
wherein the tubing manifold further comprises one or more baffles positioned around the elongate body, wherein each baffle of the one or more baffles defines a central opening that receives a portion of the elongate body.
