Abstract
The invention discloses an electric power gas chromatography sample-preparation exhaust device which is characterized by comprising a base; the base is provided with a fixing rod and a lifting rod; the fixing rod is provided with a swing rod; one end of the swing rod is rotatably connected with the fixing rod, and the other end of the swing rod is provided with an injector; the lifting rod is provided with an arc-shaped track; the injector presses against the inner side of the arc-shaped track; the exhaust device also includes a driving device for driving the lifting rod to move up and down. When the injector swings, gas in a sample is fully separated due to a centrifugal force action, at the same time, the arc-shaped track moves upwards, and the injector is compressed to make air discharged. Due to the adoption of the technical scheme, the exhaust step in the process of sample preparation can be realized, and the sample preparation time is greatly saved.
