A preferred sample introduction apparatus includes a wall that defines a channel, with the channel being configured to receive a sample and being adapted to engage in fluid communication with the separation column of a chromatographic apparatus. Preferably, a coating of semi-conductive material is arranged adjacent to at least a portion of the wall. Additionally, a heater controller is provided which electro-magnetically communicates with the coating. So configured, the coating, in response to receiving energy from the heater controller, increases in temperature, thereby increasing a temperature of the sample.
