Method for detecting sample supply condition, and analyzer

Abstract

The present invention relates to detecting method and analyzing tool for sample supply state. The analyzer (1) having a flow channel for moving a sample and also having a working electrode (15) and a counter electrode (16) that have active sections (15c, 16c, 16d) coming into contact with the sample supplied to the flow channel, and used by being installed on an analysis device. The active sections (16c, 16d) of the counter electrode (16) include a first active section (16c) and a second active section (16d) that are separated in the flow channel. The working electrode (15) and the counter electrode (16) have contact ends (15a, 16a) that are in contact with terminals of the analysis device when the analyzer (1) is installed on the analysis device. At least one of the working electrode (15) and the counter electrode (16) has a first electrode section (16B) having the contact end (16a) and the first active section (16c) and also has a second electrode section (16C) having the second active section (16d).

Description

technical field [0001] The present invention relates to a technique for detecting whether or not a sample is properly supplied to a flow path in an analysis tool including a flow path such as a biosensor. Background technique [0002] In the case of analyzing a specific component contained in a biochemical sample, a method in which an analysis tool is used in combination with an analysis device is employed. For example, when measuring the concentration of glucose (blood sugar level) contained in blood, a method of using a biosensor in combination with a blood sugar level measuring device is used. [0003] Examples of biosensors include those shown in FIGS. 9 to 11 . The biosensor 8 shown in these figures measures blood glucose levels electrochemically and has a structure in which a cover 82 is bonded to a substrate 80 via a spacer 81 . A gap 83 is provided on the spacer 81 , through which a capillary 84 is defined between the base plate 80 and the cover 82 . The capillary ...

Problems solved by technology

Therefore, compared with the blood glucose level measurement device 9 (refer to FIG. 12 ) used for the biosensor 8 (refer to FIGS. 9 to 12 ) that is not provided with the detection electrode 88, the device structure is more complicated and requires more control.

As a result, in the blood sugar level measuring device 9', compared with the blood sugar level measuring device 9 (refer to FIG. 12), the structure becomes more complicated, and the manufacturing cost increases.
