Abstract
An injector with a vaporization chamber for gas chromatographic apparatus includes a heater to heat the chamber and a pierceable septum to seal an end of the chamber. At least a heat conducting element is removably mounted between the septum and the heater. One or more elements are positioned adjacent to the septum and are in fluid communication with a source of carrier gas and a discharge outlet. The elements define paths with forced run for washing the septum and for feeding the vaporization chamber.
