1. An apparatus for analyzing a fluid, comprising:
- a heating chamber comprising at least one heating element suitable for heating the fluid to a heating temperature and for imparting a first space velocity to the fluid;
a heating controller suitable for controlling the heating temperature of the fluid;
at least one catalyst sample provided substantially in-line following the heating chamber and suitable for interacting with a first portion of the fluid having a second space velocity;
at least one vent suitable for venting, prior to interacting with the catalyst sample, of a second portion of the fluid, thereby imparting the second space velocity to the first portion of the fluid;
at least one mass flow controller for controlling flow of a mass-flow controlled one of the interacted first portion of the fluid; and
at least three outputs, comprising;
a first output suitable for outputting the mass flow controlled one of the interacted first portion;
a second output suitable for substantially directly outputting a pre-treated one of the interacted first portion; and
a third output suitable for substantially directly outputting the interacted first portion.

Abstract
Disclosed herein is a method of separating variations in the mass flow of gas through a catalyst from the thermal load observed by the temperature control system in a test bench. The method may include separating the temperature control component from the mass flow control component.

12. A method for analyzing at least one fluid, comprising:
-
heating at least one fluid in a heating chamber, the heating chamber comprising at least one heating element and at least one heating control for controlling a heating temperature of the at least one fluid; venting at least a second portion of the at least one fluid after said heating; interacting a first, non-vented portion of the at least one fluid with a catalyst after said venting; controlling a flow of the interacted first, non-vented portion of the at least one fluid utilizing at least one mass flow controller; outputting at least a flow contolled one of the interacted first, non-vented portion of the at least one fluid, and a non-flow controlled one of the interacted first, non-vented portion of the at least one fluid. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
