DETERMINATION METHOD FOR AUTOMATICALLY IDENTIFYING ANALYTE LIQUID AND STANDARD SOLUTION FOR BIOSENSOR

摘要

A determination method wherein a biosensor comprises a electrode portion including a counter electrode formed on an insulating substrate and a measuring electrode and a reagent layer which reacts with a sample liquid supplied to the electrode portion, and a substrate included in the sample liquid is determined by measuring the value of a current which flows when a voltage is applied to the electrode portion of the biosensor by a driving voltage of a measuring unit. A standard solution used for control the measuring accuracy of the measuring unit includes a reducing substance. Consequently, when the standard solution is measured, a great change appears in the current waveform between the times t0 and t1 as shown in Fig. 6 because of the presence of the reducing substance. Therefore, the analyte being measured can be easily identified as the standard solution or a sample liquid.
