Abstract:
1. A flow rate sensor adjustment method in an analysis apparatus including a flow rate sensor for measuring a travel time of a sample passing through a resistive body, the flow rate sensor including a tubular member with a straight part running straightly and at least one sensor for detecting an interface between a first fluid and a second fluid both traveling in the straight part, the straight part being inclined relative to a horizontal direction, the method causing the interface to travel by what corresponds to a predetermined amount of the first fluid or the second fluid and adjusting a position of the at least one sensor with respect to the traveled interface, wherein the at least one sensor includes a plurality of sensors, a sensor located at a most upstream side or a most downstream side among the plurality of sensors is aligned with respect to the interface, the interface is repeatedly caused to travel by what corresponds to a predetermined amount of the first fluid or the second fluid, and positions of the plurality of sensors other than the sensor located at the most upstream side or the most downstream side in the plurality of sensors are adjusted every time the interface is caused to travel.
