DENSITOMETER, TEST PIECE FOR THE DENSITOMETER, BIOSENSOR SYSTEM, AND METHOD FOR FORMING TERMINAL OF THE TEST PIECE

Document Type and Number:

WIPO Patent Application WO/1999/005516

Kind Code:

A1

Abstract:

A densitometer for measuring an objective component with a test piece suitable for the component; a test piece for the densitometer; a biosensor system; and a method for forming a terminal of a test piece. An identifying electrode (104) is provided in addition to an anode (102) and a cathode (103) in order to recognize the type of the attached test piece on the measuring instrument (101) side. Only when a test piece (115) suitable for the instrument is attached, therefore, the instrument can measure the component in a liquid sample by the electrical connection between the identifying electrode and the terminal of the attached test piece. Further, a measuring instrument (251) senses a variation for working curve information selection in order to select the working curve information corresponding to the production lot of the attached test piece to compensate the error of the concentration of the component.
