Sensor, Measuring Device, And Measuring Method
First Claim
1. A sensor comprising:
- a sample-holding unit including a space for holding a sample including a first analyte and a second analyte;
a sample-supplying port for supplying said sample to said sample-holding unit, the port being connected to the space;
a detecting unit for carrying out an electrochemical measurement of said second analyte, the unit being provided in said sample-holding unit;
an optical measuring unit for carrying out an optical measurement of said first analyte, the optical measuring unit being provided in said sample-holding unit; and
a reagent-holding unit for holding a reagent for said optical measurement, the reagent-holding unit being provided in said sample-holding unit;
wherein in a flowing direction of said sample supplied from said sample-supplying port in said sample-holding unit, said sample-supplying port, said detecting unit, and said reagent-holding unit are positioned in the order recited.
