The application provides a sample analysis system which maintains the processing capability and also control the arrangement area. The sample analysis system 100 comprises two execution assemblies 101, each execution assembly including: a measuring module for measuring a first measuring unit 10 and a second measuring unit 20 of a sample, and a conveying unit 30 configured to correspond to the measuring module. The conveying unit 30 includes a first conveying path 31 for receiving from an upstream side a sample support 120 equipped with a sample container 110 and sending the sample support to a downstream side, and a second conveying path 32 for receiving conveying the sample support 120 received by the first conveying path 31 to the measuring module. The second conveying path 32 distributes and supplies the sample container 110 to the first measuring unit 10 and the second measuring unit 20 by making the sample support 120 move back and forth between the first measuring unit 10 and the second measuring unit 20.
