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.
