Abstract of the Disclosure Disclosed is a process chromatograph including a column for separating fluid samples into their individual components, and a density- responsive detector connected to the column output to produce a pressure signal representing the concentration of the separated components. The column and associated elements are contained within a thermally-insulated housing the interior spaces of which are heated and maintained at a set- point temperature by a temperature regulating system. Heat energy is sup- plied by steam to one section of a two-section tubular heat-exchanger. A stream of air is caused to flow through the other section and into the housing interior, to transfer heat thereto. The rate of heat transfer is automatically controlled by a thermostatic control which continuosly adjusts the flow of air through the heat exchanger so as to maintain the interior temperature at a desired set-point.
