Patent ID: 8895296

Claim:
A nucleic acid analyzer comprising: a carousel rotatable about a rotation axis, a plurality of reaction containers held along a circumferential edge of the carousel, and a plurality of detectors each including a light source for irradiating the reaction container with excitation light and a detection element for detecting fluorescence from a reaction liquid in the reaction container, wherein: the detectors are arranged along the circumference of the carousel, and each of the plurality of detectors are configured to perform fluorescence measurement independently of one another, the carousel is configured for operation based on a cycle comprising: a container setting period for stopping the carousel in order to place or remove the reaction container, and a fluorescence measurement period for rotating the carousel at a constant speed, the length of the container setting period and the length of the fluorescence measurement period are constant, and the container setting period and the fluorescence measurement period are repeated in a predetermined cycle.
