Flow passage device and testing system using the same

摘要

A real time analysis in accordance with temperature change and highly sensitive detection are permitted. A flow passage device has a flow passage (1) and is able to heat a fluid in the flow passage. A state of the fluid in the flow passage is observable using light. The flow passage device includes a first member (2) including an observation surface (3) and an upper inner wall surface (4), and a second member (5) including a lower inner wall surface that opposes the upper inner wall surface (4) and that is part of inner walls of the flow passage. A heating resistor (6) having a reflective surface that reflects light is provided on the lower inner wall surface. The light reflected by the reflective surface passes through the upper inner wall surface (4) and the observation surface (3).

1. A flow passage device having a flow passage, wherein the flow passage device is able to heat a fluid in the flow passage, and wherein a state of the fluid in the flow passage is observable using light, the flow passage device comprising:
an observation surface used for observing a state in the flow passage; a first inner wall surface that is part of inner walls of the flow passage; and a second inner wall surface that opposes the first inner wall surface and that is part of the inner walls of the flow passage, wherein a heating resistor is provided in the second inner wall surface, wherein the heating resistor has a reflective surface that reflects light, and wherein the second inner wall surface is, aside from the heating resistor, provided with a reflective member that does not produce heat, wherein the reflective member is provided adjacent to the heating resistor with a gap therebetween.
