Abstract
There is provided an analysis tool having a plurality of electrodes formed on a substrate. The plurality electrodes include two or more first electrodes having working electrodes and one or more second electrodes having counter electrodes. The analysis tool may also additionally have a flow channel for transferring a sample. The electrodes are preferably disposed so that the working electrodes and the counter electrodes have a symmetrical positional relationship with each other in a transferring direction of the sample in the flow channel.

8. An analyzer for performing analysis of a sample using an analysis tool, the analysis tool having first and second working electrodes and at least one counter electrode, the analyzer comprising:
-
an electric current measurement component that measures a response electric current when a voltage is applied between the first and second working electrodes and the at least one counter electrode; a detection component that detects a shortage of the sample supplied to the analysis tool by comparing a first response electric current, obtained when a voltage is applied between the first working electrode and the counter electrode, with a second response electric current, obtained when a voltage is applied between the second working electrode and the counter electrode; and an analysis component that performs analysis of the sample based on at least one of the first or second response electric currents.
