Optical measurement device for reaction vessel and method therefor

A method for operating an optical measurement device, comprising:

• providing a first optical fiber and a second optical fiber, wherein the first optical fiber includes opposing first and second ends, and the second optical fiber includes opposing third and fourth ends;
• providing a first reaction vessel and a second reaction vessel, wherein the first reaction vessel comprises an opening to a first interior, and the second reaction vessel comprises an opening to a second interior;
• providing a first measurement device for receiving emissions from the first and second reaction vessels, wherein the first measurement device comprises a first photoelectric element and a first inlet optically connected with the first photoelectric element;
• providing a light guide stage comprising a light guide plate coupled to the first end of the first optical fiber and the third end of the second optical fiber;
• providing a nozzle head coupled to and movable with the light guide stage, comprising:
• a suction-discharge mechanism;
• and
• a plurality of nozzles connected to the suction-discharge mechanism, each of the plurality of nozzles comprising a detachable dispensing tip, wherein suction and discharge of gases by the suction-discharge mechanism causes suction and discharge of liquids by the plurality of detachable dispensing tips;
• driving the light guide stage in a vertical direction relative to the openings of the first and second interiors using a stage transfer mechanism;
• simultaneously optically connecting the first end of the first optical fiber with the first interior of the first reaction vessel, and the third end of the second optical fiber with the second interior of the second reaction vessel;
• driving a connecting end arranging body along a first predetermined path to a first measurement position using an arranging body transfer mechanism, wherein the connecting end arranging body supports the second end of the first optical fiber and the fourth end of the second optical fiber along the first predetermined path;
• optically connecting the second end of the first optical fiber with the first photoelectric element via the first inlet so that light based on an optical state within the first reaction vessel is transmitted from the first reaction vessel to the first photoelectric element;
• driving the connecting end arranging body along the first predetermined path to a second measurement position using the arranging body transfer mechanism;
• and
• optically connecting the fourth end of the second optical fiber with the first photoelectric element so that light based on an optical state within the second reaction vessel is transmitted from the second reaction vessel to the first photoelectric element.
