Abstract:
1. A detection device comprising: an optical device, wherein the optical device emits light based on an inspection target material that exists within a fluid sample, wherein the inspection target material is adsorbed onto a surface of the optical device; a suction section adapted to suck the fluid sample in the optical device; a light source adapted to irradiate the optical device with light; a light detection section adapted to detect light emitted from the optical device; and a control section adapted to perform drive control on the suction section, wherein the control section sets a suction flow velocity of the fluid sample in the optical device to V wherein the emitted light is a Raman scattering light of the inspection target material within the fluid sample, the light detection section detects the Raman scattering light of the inspection target material, the control section performs switching from the first mode to the second mode in response to a level of the signal from the light detection section exceeding a first threshold level, the control section performs switching from the second mode to the first mode in response to the level of the signal from the light detection section falling below a second threshold level lower than the first threshold level, the first mode is an adsorption mode wherein an external force generated by the suction section is less than an adsorption force between the inspection target material and the surface of the optical device, and the second mode is a break away mode in which the external force generated by the suction section is greater than the adsorption force between the inspection target material and the surface of the optical device.
