| 摘要 |
The invention concerns an apparatus for preparing samples for analysis having at least a liquid-injecting needle (6), at least a column (32) for receiving the injecting needle, at least a tube (48), device (6, 26) for the tube and the column relative horizontal displacement between a position of coincidence in which the column bottom aperture (36) extends above the tube top aperture (50), and a relative lateral offset position of the two apertures (36, 50), and adapted device (6, 60) for the tube (48) and the column (32) relative vertical displacement such that in position of coincidence, the apertures (36, 50) interpenetrate, including vertical guide device for either the tube (48) or the column (32). The vertical guide device is adapted to operate the guiding under horizontal loading effect.
