| 摘要 |
The present invention relates to an analytical tool ( 1 A) which includes a flow path ( 8 A) for moving a sample, a sample introduction port ( 73 A), and a liquid reservoir ( 7 A) for reserving the sample to be introduced into the flow path ( 8 A) The flow path ( 8 A) and the liquid reservoir ( 7 A) are configured to cause suction force to act on both the flow path and the liquid reservoir. The suction force to act on the liquid reservoir ( 7 A) is smaller than the suction force to act on the flow path ( 8 A). The sectional area of the liquid reservoir ( 7 A) in a perpendicular direction which is perpendicular to the movement direction of the sample is set larger than the sectional area of the flow path ( 8 A) in the perpendicular direction. Preferably, the capacity of the liquid reservoir ( 7 A) is set larger than the capacity of the flow path ( 8 A).
