Abstract
The auto-sampler for chromatographs includes a sampling needle, a pipe, a pump portion, and a connecting mechanism configured to connect the sampling needle and the pipe. The connecting mechanism includes a first component fixed to the sampling needle, a second component fixed to the pipe, a fixing component, and a packing. The fixing component fixes the first component and the second component using screwing of screws while the end surface of the sampling needle and the end surface of the pipe are in contact with the packing. As a result, dead volume at the connecting portion between the sampling needle and the pipe is reduced.
