Chromatographic system temperature control system

A chromatographic system, comprising:

• a first chromatographic component selected from a first group of chromatographic components consisting of a transport line, a sample loop, and a column, each of the first group of chromatographic components having electrically-conductive material;
• a second chromatographic component selected from a second group of chromatographic components consisting of a valve and a detector;
• a first electrically-controlled heating element associated with the electrically-conductive material of the first chromatographic component;
• a second electrically-controlled heating element associated with the second chromatographic component;
• a first temperature sensor associated with the first chromatographic component, the first temperature sensor generating a first temperature sensor signal;
• a second temperature sensor associated with the second chromatographic component, the second temperature sensor generating a second temperature sensor signal;
• a power supply;
• a temperature controller, the temperature controller having a processor, a first electrically-controlled heating element output, a second electrically-controlled heating element output, a first temperature sensor input, and a second temperature sensor input;
• the processor adapted to receive the first temperature sensor signal at the first temperature sensor input and to construct a first actual time-temperature profile;
• the processor adapted to receive the second temperature sensor signal at the second temperature sensor input and to construct a second actual time-temperature profile;
• the processor adapted to receive a first time-temperature profile for the first chromatographic component;
• the processor adapted to receive a second time-temperature profile for the second chromatographic component selected from the group of the first time-temperature profile and the first actual time-temperature profile of the first chromatographic component;
• the processor having a first power supply control for controlling a first output from the power supply to the first electrically-controlled heating element output;
• the processor having a second power supply control for controlling a second output from the power supply to the first electrically-controlled heating element output;
• the processor adapted to alter the first output from the power supply so the first actual time-temperature profile approaches the first time-temperature profile;
• the processor adapted to alter the second output from the power supply so the second actual time-temperature profile approaches the second time-temperature profile.
