Patent ID: 7908901

Claim:
A radiant energy heated oven apparatus comprising: a radiant energy heated oven including: a heated zone, a closed-loop assembly with a coolant supply reservoir, a coolant chamber in thermal contact with the radiant energy heated oven including: a coolant inlet via a conduit from said coolant supply reservoir and a coolant outlet where spent coolant is returned to the coolant supply reservoir, where the coolant inlet directs a coolant into the chamber, the coolant absorbs thermal energy from the oven and the outlet directs spent coolant out of the chamber, cooling the oven to a desired temperature, at a desired rate or at a controlled rate, wherein the radiant energy is microwave energy, radio wave energy or some other radiant energy capable of heating the heating zone; a chromatography column disposed within the heating zone of the oven, where the oven is adapted to heat the column to a desired temperature at a desired rate or to heat the column according to a temperature programmed heating profile; and wherein the apparatus is adapted to decrease a sample cycled time of an analytical instrument including the apparatus.
