ABSTRACT:
This invention concerns a device for inserting samples into a chromatography column.
The device comprises a syringe mounted on a carriage, a sample-holder consisting of a circular plate and a control system linking the syringe and sample-holder. The plate and syringe axes are parallel, the axis of the sample-holder cell is at an angle of at least 10.degree. to the horizontal, each cavity for a sample-holder cell is followed in turn by an aperture and a cavity for a cell containing a rinsing liquid, and a control system is provided so that during injection of the sample into the chromatography column, the syringe needle passes through the aperture.
The proposed device is specially adapted for chromatographic analysis of samples in the trace form.
