Abstract: In order to make it possible to predict a dissociation constant at an initial stage of reaction, a concentration sensor for a sample is provided on a downstream side of a mass sensor. This makes it possible to learn concentration of a sample solution at the time when a mass is detected by the mass sensor. When the concentration and the mass are substituted in a predetermined logical expression, it is possible to obtain a predicted value of a dissociation constant. The concentration sensor is a capacitor constituted by electrodes opposed to each other. Since a dielectric constant changes when analytes are present between the electrodes, it is possible to detect analyte concentration according to the dielectric constant. Since it is possible to reduce a size of the capacitor, it is possible to keep a size of a micro-reactor small. Note that the mass sensor outputs a resonance frequency of a quartz resonator. A measuring apparatus can calculate a mass from transition of this frequency.

Abstract: In order to provide a reactor, a micro reactor chip, and a micro reactor system which can maintain high sensitivity without residual stresses on a crystal oscillator and unwanted oscillation modes, both surfaces of an AT-cut crystal plate 100 is deposited or sputtered with gold to prepare a detection electrode 601, an opposite electrode 602, and wiring to both electrodes. A resist is then formed on a cleaned silicon wafer. Polydimethylsiloxane (PDMS) is then poured onto the silicon wafer and allowed to cure. The PDMS is then peeled from the silicon wafer to form a groove 500 in the PDMS. The PDMS is then laid on the crystal plate. When the crystal substrate side is then irradiate with ultraviolet light the silicon-carbon bond between the crystal and the PDMS is cut, thus causing the crystal and the PDMS to bond to each other by means of a siloxane bond. The liquid introduction port and the liquid discharge port are then cut to form the reactor.
