A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Results of measurements are recorded in a memory device on one end of the heater tube on which the deposits were made.

Apparatus and method for determining the thermal stability of fluids

A cooling apparatus for a radiant energy heated oven is disclosed, where the cooling apparatus cools the oven by directing a flow of coolant through a chamber in thermal communication with the oven resulting in sub-ambient cooling, sub-ambient holds, and in chromatography instruments, higher sample throughput by reducing cycle time or column cool down time.
