体試料注入装置。 In a liquid sample injection device, the cross section is Y-shaped, a hole is made in the center for the sample suction needle to pass through, and a ring spring is inserted around the outer circumference of the center so that the needle seal always presses against the sample suction needle. The needle seal is characterized in that it enables self-sealing by being pressed by the hydraulic pressure in the sealing chamber, and the outer periphery with a Y-shaped cross section maintains airtightness against the sealing chamber wall by the hydraulic pressure, thereby extending the life of the needle seal. Liquid sample injection device.
