Abstract

An autosampler includes: a sample cooling unit that is brought into thermally contact with a bottom surface of a sample rack so as to cool a sample accommodated in the sample rack; a condensed water receiver that has at least one hole on a bottom surface thereof, and is provided below the sample rack for receiving water condensed around the sample rack; a discharging passage configured in such a manner that a droplet falling from the at least one hole flows therein.

First claim

The invention claimed is:

1. An autosampler comprising:
a) a sample cooler that is brought into thermal contact with a bottom surface of a sample rack to cool a sample accommodated in a vial, wherein the sample rack supports a bottom surface of the vial;
b) a condensed water receiver provided below the sample rack, for receiving water condensed around the sample rack, with at least one hole passing through a quadrangular bottom surface of the condensed water receiver;
c) a discharging passage formed in such a manner that a droplet falling from the at least one hole flows into this discharging passage;
d) a cover member that is provided separately from the sample rack and the condensed water receiver and is disposed between the sample rack and the sample cooler to cover the sample cooler from above, and is disposed between the condensed water receiver and the sample rack, the cover member being thermally conductive at least in its top surface;
wherein the condensed water receiver is placed below a lowermost surface of the cover member and receives water condensed on the cover member.

2. The autosampler according to claim 1 , wherein:
the condensed water receiver includes an opening and a concave portion which is the quadrangular bottom facing surface;
a metal block included in the sample cooler is inserted into the opening; and
the concave portion is formed in such a manner as to slope down toward the hole.
