[0027] Manually clamp the syringe body onto the syringe injection assembly, and fix the syringe push rod on the injector slide table.

[0028] After the robotic arm clamps the sample vial at the sample vial placement position, the rotary cylinder swings. After rotating 180 degrees, the robotic arm clamps the extraction vial and places it at the extraction vial placement position.

[0029] The two-axis robotic arm drives the syringe injection assembly to move up and down, installs the syringe and the 5um filter, and after the robotic arm swing arm rises and swings, it reaches above the sample vial placement position to draw liquid.

[0030] After drawing the liquid, swing the robotic arm to the unhooking device position, move the swing arm upward to complete the unhooking of the 5um filter, continue to move the swing arm to the filter position, after the injection cylinder moves, lower the swing arm to complete the installation of the 0.25um filter.

[0034] The two-axis robotic arm is composed of two servo motors, synchronous pulleys, and linear guide rails, and can realize the lifting and swinging of the upper swing arm.

[0037] The extraction vial placement position places extraction vials, which has the same slot structure as the sample vial placement position.

[0038] The extraction vial and the sample vial are switched by about 180° through the rotary cylinder, so that the sample can be extracted or injected without changing the swing angle of the robotic arm.

[0039] The optical fiber detection position is used to judge the liquid separation height in the extraction vial to achieve quantitative injection of liquid.

[0040] The solid waste bin is equipped with a rotary sealing structure, which can collect used waste filters and be transferred out of the glove box after manual closing of the lid.
