An analyzer (A) includes a measurer () for measuring an electro-physical quantity of a sample, and an acceleration measurer () for computing the acceleration of change of the electro-physical quantity such as a current measured by the measurer (). The fail determination as to whether or not a predetermined condition necessary for performing analysis of the sample is satisfied is made based on the acceleration computed by the acceleration measurer (). As a result, the fail determination in the analysis process of the sample can be performed accurately.

Fail judging method for analysis and analyzer

An analyzer (A) includes a current measurer () for measuring the current flowing between paired electrodes (), () when a sample is introduced to the reagent layer () of a sensor () and voltage is applied across the electrodes, while also including a processor () for analyzing the sample based on the current after a predetermined reference time point. The analyzer (A) further includes a fail determiner () which monitors the change of the current before and after the reference time point and determines that the sensor () is improper when the current change does not correspond to a predetermined current change.
