1. A method for controlling at least two chromatographic components in a chromatographic system, comprising:

  • determining a power/temperature relationship for a first component;

    determining a power/temperature relationship for a second component;

    receiving a time/temperature profile for the first component;

    receiving an input identifying whether a time/temperature profile for the second component will track an actual time/temperature profile of the first component;

    applying power to the first component to alter a temperature of the first component according to the power-temperature relationship for the first component;

    obtaining a temperature measurement of the first component;

    constructing the actual time-temperature profile of the first component;

    adjusting a first component power supplied to the first component to alter the temperature of the first component according to the power-temperature relationship for the first component as determined by the temperature measurement of the first component;

    applying a second component power to the second component to alter the temperature of the second component according to one of the power-temperature relationship for the first component and the actual time-temperature profile of the first component;

    obtaining a temperature measurement of the second component;

    adjusting the first component power supplied to the first component to alter the temperature of the second component according to one of the group of relationships consisting of the power-temperature relationship for the first component and the actual time-temperature profile of the first component as determined by the temperature measurement of the second component.
