ABSTRACT:
An absorption spectrometric analysis microchip with a chamber for holding a sample, a chamber for holding a reagent which reacts with this sample, a mixing chamber for mixing the reagent with the sample with the formation of a mixture and a sensing part with a sensing chamber for holding the mixture with a light incidence surface for the entry of light into the sensing chamber and a light exit surface for emergence of light from the sensing chamber. At least one of the light incidence surface and light exit surface is located in a recess area of the sensing part.
