Analyzing instrument, analyzing device, and method of manufacturing analyzing instrument
First Claim
1. An analyzing instrument comprising:
- a capillary for moving and retaining a sample liquid;
a sample liquid inlet for introduction of the sample liquid into the capillary;
measuring electrodes for measuring a target component in the sample liquid;
liquid introduction regulator for controlled introduction of the sample liquid into the capillary; and
one or more detecting electrodes provided separately from the measuring electrodes for detecting the controlled introduction of the sample liquid into the capillary.

Abstract
An analyzing instrument (2) according to the present invention includes a capillary (6), a sample liquid inlet (42), and a liquid introduction controller for a controlled pattern of introduction of the sample liquid into the capillary. The capillary (6) preferably includes a common passage (60) and a plurality of individual passages (61–63) connecting to the common passage. In this arrangement, the liquid introduction controller selects for each of the individual passages (61–63) whether or not the sample liquid is introduced therein. The liquid introduction controller includes, for example, one or more through-holes (51–53) each communicating with e.g. the individual passages (61–63). The liquid introduction controller preferably selects for each of the individual passages (61–63) whether or not the sample liquid is introduced therein, by a selection whether or not the corresponding one of the through-holes (61–63) is opened or closed.

22. A method of manufacturing an analyzing instrument comprising:
- a capillary for moving and retaining a sample liquid;
a sample liquid inlet for introduction of the sample liquid into the capillary;
a common passage in the capillary;
a plurality of individual passages located farther away from the sample liquid inlet than is the common passage and connected to the common passage; and
