Abstract:
An instrument for programmable generation of volatilized material, comprising:at least one flow passage having a first open end; a liquid supply operable to supply liquid material to the flow passage; at least one heater arrangement adapted to heat the flow passage to a temperature sufficient to volatilize material in liquid form in the flow passage such that the volatilized material expands out of the open end of the flow passage; a controller operable to control operation of the heater and control operation of the liquid supply; a monitoring arrangement operable to supply heater performance data to the controller, the data being used by the controller to supply power to the heater arrangement or to cut off power to the heater arrangement to maintain the heater arrangement at a desired temperature range; and a memory operable to store parameters associated with the instrument.
