DEVICE FOR SAMPLING AND ENTERING SAMPLES INTO ANALYZER OF COMPOSITION Russian patent published in 2019 - IPC G01N30/18 

Abstract RU 2697930 C1

FIELD: instrument engineering.

SUBSTANCE: invention relates to analytical instrument-making and can be used in devices for automatic collection and input of liquid samples, for example, in a gas chromatograph. Summary: device comprises dosing unit with washing unit. Washing unit contains a hollow nozzle installed on body (2) of the dosing syringe from the side of its piston (7) input. Cavity (8) of the nozzle is connected to the working cavity of the syringe and to the vessel with the flushing fluid. Seal element (3) is installed between end face of syringe body (2) and body (1) of hollow nozzle with possibility of controlling degree of its compression by nut (4) interacting with body (1) of hollow nozzle. Nut (4) has stop in form of ring (5) installed in groove (6) of syringe body (2).

EFFECT: simplified design of the device, increased reliability of its operation.
