Sample analyzing method and sample analyzing device

摘要

This invention relates to a technique for analyzing a sample. A sample analyzer ( 1 ) provided by the invention includes: a voltage applier ( 12 ) for applying a voltage to a reaction field which includes a sample; a response measurer ( 13 ) for measurement of a response to the voltage applied to the reaction field; a selector ( 11 ) for selecting a first voltage application state for measurement of a first response for use in calculation necessary for analyzing the sample or a second voltage application state for measurement of a second response for use in determining whether or not the reaction field has been supplied with a target amount of the sample; an arithmetic operator ( 17 ) for calculation necessary for analyzing the sample based on the first response; a determiner ( 17 ) for determination, based on the second response, on whether or not the reaction field has been supplied with the target amount of sample; and a controller ( 15 ) which makes the selector select the second voltage application state after making the selector select the first voltage application state.
