Abstract
A sample pretreatment device of an aspect of the present invention includes a conveyance mechanism (22) including a Z-axis guide (223) that linearly moves in two axes of an X axis and a Y axis and expands/contracts in a Z-axis direction on a table (21) where a unit that performs each step of pretreatment is arranged. The Z-axis guide (22) is integrally provided with a liquid handler (224) and a grip handler (225) oriented in opposite directions to each other. A side wall of a housing (20) on the autosampler side is provided with a sample conveyance opening (201). When pretreatment of a sample ends, the Z-axis guide (223) is moved to a position close to the opening (201) in a state where a gripper (228) grips a pretreated plate. An arm (227) enters a housing of the autosampler through the opening (201) and an opening formed in the autosampler, and sets a plate at a predetermined position. Thus, the sample pretreatment device can eliminate the labor of the worker setting a pretreated sample in the analysis device.
