Abstract
The present invention relates to a technique for measuring the concentration of a particular component in a sample liquid using a test tool (). The test tool () includes a first through a third detection elements (-) arranged in the mentioned order in the moving direction of the sample liquid for measuring an electro-physical quantity. The present invention provides a concentration measuring method which includes a first detection step for detecting whether or not liquid conduction is established between the first and the second detection elements (), a second detection step for detecting whether or not liquid conduction is established between the second and the third detection elements (), a measurement step for measuring an electro-physical quantity by using the first through the third detection elements (-), and a concentration computation step for computing the concentration of the particular component based on the electro-physical quantity. The present invention also provides a concentration measuring apparatus () for realizing the concentration measuring method.
