PROBLEM TO BE SOLVED: To accurately calibrate a measuring error caused by a drift component included in a measured result, in a measuring instrument provided with a flow passage for supplying a sample on a thin film layer, and a measuring method using the measuring instrument. SOLUTION: A change with the lapse of time is preliminarily measured when a buffer used in an objective measurement flows at a flow velocity same to that in the objective measurement, in the flow passage 60, a result therein is stored in a storage means inside a signal processor 20, and the measured result when the buffer is supplied in the objective measurement is calibrated by a calibration means inside the signal processor 20, based on the result in the preliminary measurement.
