Detection device
First Claim
1. A detection device comprising:
- a sensor chip;
a suction section adapted to suck a fluid sample including a sample molecule to thereby adsorb the fluid sample to the sensor chip;
a light source adapted to irradiate the sensor chip with light;
a light intensity adjustment section adapted to adjust intensity of the light irradiating the sensor chip;
a light detection section adapted to detect the sample molecule using light reflecting the sample molecule adsorbed on the sensor chip; and
a control section adapted to control the suction section and the light intensity adjustment section,wherein assuming that a flow velocity of the fluid sample on the sensor chip in a first mode including a period in which the light detection section performs the detection is V1, and the flow velocity of the fluid sample on the sensor chip in a second mode is V2, the suction section controls the flow velocity of the fluid sample so that V2>
V1 is fulfilled,assuming that the intensity of the light on the sensor chip from the light source in the first mode is L1, and the light intensity on the sensor chip in the second mode is L2, the light intensity adjustment section controls the light intensity so that L2>
L1 is fulfilled, andthe control section switches between the first mode and the second mode based on a signal from the light detection section.

Abstract
A detection device includes a sensor chip, a suction section adapted to suck a fluid sample to the sensor chip, a light source adapted to irradiate the sensor chip, a light intensity adjustment section adapted to adjust intensity of the light, a light detection section adapted to detect the light reflecting the sample adsorbed to the sensor chip, and a control section adapted to perform drive control on the suction section. The control section sets the suction flow velocity to V1 in the first mode in which the light detection section performs the detection, and sets the suction flow velocity to V2 (V2>V1) in the second mode. The light intensity adjustment section sets the light intensity to L1 in the first mode, and sets the light intensity to L2 (L2>L1) in the second mode. The first and second modes are switched based on the signal from the light detection section.
