Automatic analysis device and method for installing separation column in automatic analysis device

The present invention is provided with: an identification mechanism (15, 16, 17, 18, 19) that reads an identifier (401) provided to a separation column (10, 11, 12, 13, 14) when the separation column (10, 11, 12, 13, 14) is set to an installation position; a computer (4) that determines whether or not the identification information of the identifier (401) read by the identification means (15, 16, 17, 18, 19) matches a pre-registered setting pattern; and a display unit (2) that notifies a warning when the computer (4) determines that the identification information does not match the setting mode. As a result, provided are: an automatic analysis device that performs chromatographic analysis by separately using a plurality of types of separation columns, said automatic analysis device being capable of setting a separation column of a specified type at a target position; and a method for setting a separation column in an automatic analysis device. 具备：识别机构(15、16、17、18、19)，其在分离柱(10、11、12、13、14)被设置到设置位置时读取设于分离柱(10、1
