Abstract

An analysis systemincludes a plurality of spectrophotometers, a memory storage, and a control terminal. The spectrophotometerfurther includes a light source, a light detector, and an optical element that introduces light from the light sourceto the light detector. The memory devicestores the information as the control informationrelative to the light amount of the light detected by the light detectorright after replacement when replacing the light source of the spectrophotometer. A replacement timing determination unitof the control terminalreads out a control informationin the memory deviceand determines the replacement timing of the optical element based on the value of the light amount information of the read-out control information
