First, the specimen solution is added to a liquid culture medium such as a physiological saline (step 103).

The sample solution has maximum absorbance at the second wavelength.

At least some of the sample solution contained in the droplets is caused to evaporate, and the concentration of pyrophosphoric acid in the sample solution in the measurement cavity is increased.

The junction member and the filter (202, 202’, 202’’) are situated between a reference electrolyte solution and a sample solution.

Subtract the optical density of the blank test solution from that of the sample solution (= corrected optical density).

A sample solution is dripped into the hole (103), and a dried sample is obtained.

By maintaining the sample quantity even once there is no longer any contact with the sample solution, the sensor is simultaneously protected from drying out.

An array of nanochannels (106) spans the junction member and provides fluid communication between the electrolyte solution and the sample solution.

An aliquot of the sample solution is introduced into the container with a pipette to be calibrated.

An immunoassay for detecting the presence of an analyte in a sample solution is disclosed.
