PROBLEM TO BE SOLVED: To provide a calibration system capable of performing highly accurately the calibration of a blood component measuring apparatus by suppressing sedimentation of solid particles in a suspension liquid to be used as a calibration liquid, and to provide a calibration method.SOLUTION: The calibration system 10A includes: a first transmitting part 44 and a second transmitting part 46 through which infrared rays can transmit and in which a calibration liquid 26 comprising the suspension liquid including the blood component with a predetermined concentration can circulate therein and a pump 32 supplying the calibration liquid 26 to the first transmitting part 44 and the second transmitting part 46. The pump 32 supplies the calibration liquid 26 so that the linear flow speed of the calibration liquid 26 in the first transmitting part 44 and the second transmitting part 46 becomes 0.005-4.2 cm/s.COPYRIGHT: (C)2013,JPO&INPIT【課題】較正液として使用する懸濁液中の固体粒子の沈降を抑制することにより血液成分測定装置の較正を精度良く行うことができる較正システム及び較正方法を提供する。【解決手段】較正システム10Aは、赤外光が透過可能であり且つ所定濃度の血液成分を含む懸濁液からなる較正液26を内部に流通可能な第1透過部44及び第2透過部46と、第1透過部44及び第2透過部46に較正液26を送液するポンプ32とを備える。ポンプ32は、第1透過部44及び第2透過部46内の較正液26の線流速が0.005~4.2cm/sとなるように較正液26を送液する。【選択図】図1
