The fully automatic headspace sampler is characterized in that: headspace vials manufacturer a rack, a sample cylinder rotating shaft driven by a cylinder and a sample extending from one end into a heating oven mounted on the frame, which are parallel to each other and vertically mounted on the base of the frame The cavity rotating shaft has a sample chamber mounted on the rotating shaft of the sample chamber in the heating constant temperature furnace, and a plurality of sample positions are evenly distributed around the sample chamber of the headspace sampler, and a sample tray having a plurality of sample positions uniformly distributed around the rotating shaft of the sample tray is arranged.
The vertical position of the bottom of the constant temperature furnace relative to the sample tray has a sample bottle outlet and an inlet, and is located at the axial center of the sample bottle outlet and the inlet, and is located at the bottom of the sample tray relative to the sample position and has a cylinder-driven lifting rod vertically mounted on the base. Located above the constant temperature furnace, there is a vertically downwardly driven solenoid-operated cylinder-driven dual-flow needle, which is connected to a dual-flow needle, a thermostatic heater transmission line (19), and a double-flow needle on the frame. A thermostatic heater is installed at the switching valve headspace vials manufacturer.
