Abstract
A detection system may include a reaction cell which is a container for reacting the detection sample, a light source configured to emit a detection light toward an inside of the reaction cell from one side of the reaction cell, and a photoelectric sensor arranged on the other side of the reaction cell so as to face the light source and configured to receive the detection light transmitted through the reaction cell and convert a signal of the received detection light into an electrical signal. A judging method may include judging whether or not the detection sample has been supplied based on whether or not the electrical signal output from the photoelectric sensor changes by sending an instruction to supply the detection sample to the reaction cell to the detection system in a state in which the light source and the photoelectric sensor are kept being operated. When the liquid level of the detection sample reaches an optical path of the detection light and an amount of change of the electrical signal output from the photoelectric sensor exceeds a specified threshold, it may be judged that the detection sample has been supplied. According to embodiments of the present invention, it is possible to easily, assuredly and quickly judge whether or not the detection sample has been supplied by existing devices in a detection system.
