Creating a calibration curve representing a relationship between a luminescence intensity of stress luminescence and a stress includes: forming a second stress luminescent film on a surface of a test piece; applying external force to the test piece; detecting external force to be applied to the test piece; photographing the test piece under application of external force; creating a luminescence intensity-stress curve plotting a relationship between a luminescence intensity of stress luminescence and a stress, on the basis of a photographed luminescent image of the second stress luminescent film and a detection value of the external force; and creating a regression equation consisting of a fourth or higher degree polynomial representing a regression relationship of the stress with respect to the luminescence intensity by polynomial regression analysis of the luminescence intensity-stress curve.

A sample pretreatment device of an aspect of the present invention includes a conveyance mechanism () including a Z-axis guide () 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 () where a unit that performs each step of pretreatment is arranged. The Z-axis guide () is integrally provided with a liquid handler () and a grip handler () oriented in opposite directions to each other. A side wall of a housing () on the autosampler side is provided with a sample conveyance opening (). When pretreatment of a sample ends, the Z-axis guide () is moved to a position close to the opening () in a state where a gripper () grips a pretreated plate. An arm () enters a housing of the autosampler through the opening () 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.
