Abstract:
1. An apparatus for solution component analysis, comprising: A plurality of grooves, which are formed on a substrate, comprising: a plurality of sample inlets; a plurality of microchannels connected to the plurality of sample inlets to enable a plurality of samples to flow therein, respectively; a mixing channel communicating with the plurality of microchannels to mix the plurality of samples within the plurality of microchannels; a reaction channel enabling the samples mixed in the mixing channel to react; a measurement channel measuring the samples having reacted in the reaction channel; and an outlet discharging the samples having completed a measurement in the measurement channel in the measurement channel, wherein the measurement channel comprises an input microchannel connected to the reaction channel to receive the reaction-completed samples from the reaction channel, a straight microchannel enabling the reaction-completed samples from the reaction channel, a straight microchannel enabling the reaction-completed samples via the input microchannel to flow straight and to transmit a light in a direction that the reaction-completed samples flow, and an output microchannel outputting the samples having passed through the straight microchannel to the outlet; optical fiber insertion grooves provided on the substrate to communicate with both ends of the straight microchannel, respectively; first and second optical fibers inserted and fixed in the optical fiber insertion grooves so that the light can be inputted and outputted via the first and second optical fibers, respectively; and a transparent layer between the measurement channel and each of the optical fiber insertion grooves.
