A device for taking a sample and for feeding into an analytical evaluation

The invention relates to a device for taking a sample of at least one fluid system (14) and for supplying the at least one sample taken in an analytical evaluation system (3, 4) with at least one sampling cylinder (1) with guided therein sampling piston (1a), whose piston rod (11) is connected to a controllable drive, which faces away from one of the piston rod (11) of the sampling plunger (1a) opening (12) of said sampling cylinder (1) to a first terminal of a 3-way valve (7) is connected, wherein the second terminal of the 3-way valve (7) via an extraction line (13) with the fluid system (14) and the third port of the 3-way valve (7) via a supply line (15) with the evaluation system (3, 4) is connected, wherein downstream of the 3-way valve (7) (in the supply line 15) opens a flushing gas (16) via a shut-off valve (8).
