Test substance detection method, detection agent composition, detection apparatus, purified water production facility, injection water production facility, purified water production method and injection water production method

Abstract

A test substance detection method includes: a step A in which a sample containing a test substance and water, a compound having a structure in which a response site and a recognition site are connected via a spacer, and a surfactant are added; and a step B in which the recognition site and the test substance interact and a response at the response site arising from the interaction is detected. Further, also provided are: a purified water production method and an injection water production method both using the foregoing; a detection agent composition containing a compound represented by Formula (1) and a surfactant; and a detection apparatus, a purified water production facility, and an injection water production facility, all using the foregoing.
