A method for analyzing a sample includes the step of irradiating a reaction portion of a sample BL and a reagentin a reaction cellA of an analysis unit with light to obtain data Dindicating optical characteristics of this portion. The method further includes the steps of irradiating a reference cellB which is not provided with a reagentwith light in a state in which the sample BL is supplied to the cell to obtain reference data Dindicating optical characteristics of this portion, irradiating a base portionC of the analysis unit with light to obtain reference data Dindicating optical characteristics of this portion, and obtaining data Dindicating optical characteristics of the sample BL before reaction with the reagentbased on the reference data Dand D

Method of optical analysis using reference cell and base plate correction and apparatus thereof

A microchannelfor transporting a specimen S using capillary phenomenon includes an analysis chamberhaving a cross-sectional area larger than those of portions located in front of and behind the analysis chamberin the direction of flow, an inflow openingthrough which the specimen S flows into the analysis chamber, and a discharge portionthrough which the specimen S is discharged from the analysis chamber. The discharge portionincludes a pair of discharge openingsandlocated opposite to each other with respect to the inflow opening. With this structure, impairment of transport of the specimen S due to the presence of a residual air bubble is avoided.
