Patent ID: 8772680

Claim:
An adaptive temperature controller system for chromatographic analysis to control and maintain the temperature of a chromatographic column assembly during heating of said chromatographic column assembly, comprising: said chromatographic column assembly including a circular coil of a fused silica chromatographic column and a metal wire, said fused silica chromatographic column and said metal wire maintained adjacent within said coil, said coil wrapped in a heat conductive outer jacket; and an adaptive temperature controller having a device for measuring resistance, said device for measuring resistance recording measurement of two members of the group consisting of power, current and voltage through said metal wire, and said device for measuring resistance determining resistance of said metal wire by application of Ohm's Law to said two members of the group consisting of power, current and voltage; a device for determining responsiveness of resistance, said device for determining responsiveness of resistance determining the change in said resistance of said metal wire relative to change in said two members of the group consisting of power, current and voltage; a power supply, said power supply in electrical communication with said metal wire; said metal wire altering temperature based on said electrical communication from said power supply; a device for controlling the output of said power supply, said device for measuring resistance outputting said determination of the resistance of said metal wire to said device for controlling the output of said power supply; said device for determining responsiveness of resistance outputting said determination of the change in said resistance of said metal wire relative to change in said two members of the group consisting of power, current and voltage to said device for controlling the output of said power supply; said device for controlling the output of said power supply determining the thermal coefficient of resistance of said metal wire based on the output of said device for measuring resistance and a temperature input; and said device for controlling the output of said power supply controlling the temperature of said metal wire based on the output of one of the group of power, voltage or current.
