A device for automatic sample successive in line with a series of samples of a liquid to be analyzed, as well as this is carried out following the use of this device

摘要

The automatic removal device successively in line, on a main pipe, a series of samples of a liquid to be analyzed in an analysis unit, characterized in that it comprises a rotary valve (1) associated with a reservoir of the sample (2) of the volume defined above, this rotary valve (1) being movable between a position in which the reservoir of the sample (2) is connected to a transfer circuit (4) mounted in bypass on the main pipe, and a loading position in which the reservoir of the sample (2) is connected to a filling circuit (7) connecting the analysis cell (3) to a source of compressed gas (8), equipped with a shut-off valve (9).
