Abstract

A centrifugal analysis system includes a driving device, a carrying device, a number of cassettes, and an optical sensor device. The carrying device includes a tray disposed on the driving device, a number of limitation mechanisms disposed at the tray. The cassettes are detachably disposed at the tray and respectively and correspond to the limitation mechanisms. When the driving device drives the carrying device to rotate, the optical sensor circularly detects the cassettes in sequence.
