Preprocessing device and analysis system provided with same

A preprocessing device comprising:

• a setting receiving section for receiving, for each sample, setting of a plurality of types of preprocessing and a parameter for each preprocessing;
• a plurality of preprocessing sections, each being provided for performing the plurality of types of preprocessing;
• a transport section for sequentially transporting, between the plurality of preprocessing sections, a plurality of containers including a separation container with a separating layer through which a specific component in a sample is separated and a collection container for collecting a sample extracted by the separating layer;
• and
• a preprocessing execution section for controlling the plurality of preprocessing sections and the transport section so that a plurality of types of preprocessing set for each of different samples are performed simultaneously in parallel,
• wherein the preprocessing execution section performs control in such a way that preprocessing is not to be performed on different samples at a same preprocessing section at a same time.
