摘要：
An instrument for the programmable generation of volatilized material, comprising: at least one flow passage (323) having a first open end (325)； a supply of liquid (333) operable to provide liquid material to the flow passage (323)； at least one heating arrangement (310) that includes at least one resistance heater, optionally comprising a metal tube section defining the flow passage (323), the heating arrangement (310) being adapted to heat the flow passage ( 323) at a temperature sufficient for the volatilized material to exit outward from the open end (325) of the flow passage (323)； a controller (35) operable to control the operation of the heater (310) and control the operation of the liquid supply (333)； an operable control arrangement for providing the heater performance data to the controller (350), the data being used by the controller (350) to supply power to the heating arrangement (310) or to cut the power to said heating arrangement (310 ) to maintain the heating arrangement (310) at a desired temperature range； and an operable memory (351) for storing parameters related to the instrument (300), characterized in that the control arrangement includes a switch device (340) that controls the power supply to the heating arrangement (310), and The control arrangement emits data representative of a temperature-dependent resistance of the resistance heater and the controller (350) calculates the controlled resistance of the resistance heater based on the data received from the control arrangement, the controller (350) drives the element switch (340) to supply power pulses to the resistance heater at least when the controlled resistance drops below a desired resistance.Un instrumento para la generación programable de material volatilizado, que comprende: al menos un pasaje de flujo (323) que posee un primer extremo abierto (325)； un suministro de líquido (333) accionable para proporcionar material líquido al pasaje de flujo (323)； al menos una disposición cale
