  • Apparatus for taking a sample and for passing the sample to an analytical evaluation system
    Patent number: 9874578
    Abstract: An apparatus for taking a sample from at least one fluid system and for passing the sample to an analytical evaluation system connects the piston rod of the sample-taking piston with a controllable drive. A flushing gas feed opens into a feed line downstream from a three-way valve, via a shut-off valve. The three-way valve, the controllable drive, and the shut-off valve are coupled with one another so that for taking a sample, the three-way valve releases the path of the sampling line to the sample-taking cylinder, the shut-off valve is open, and the controllable drive withdraws the sample-taking piston from the sample-taking cylinder, and, for applying the sample to the evaluation system, the shut-off valve is closed, the three-way valve is switched to release the path from the sample-taking piston to the feed line, and the controllable drive pushes the sample-taking piston completely back into the sample-taking cylinder.
