  • Concentration measuring device
    Patent number: 9339218
    Abstract: A concentration measuring device having a spot-application region, and a configuration capable of measuring the concentration of an object component in the sample liquid dropped on the spot-application region, the concentration measuring device including: a light irradiation device, which is provided on a side below the spot-application region, for emitting an irradiation light having a wavelength absorbable by a coloring matter in the dropped sample liquid. The irradiation light passes through the spot-application region, thereby the sample liquid dropped on the spot-application region is irradiated with the irradiation light from the side below the spot-application region. As a result, a non-covered region in the spot-application region can be easily found by visual observation. The spot-application region is composed of, for example, a through hole formed on the supporting film and a separation membrane that blocks the through hole.
