Flow cell device

A flow cell device comprising:

• a flow path through which a fluid medium flows;
• a flow cell part in which the flow path is formed;
• and
• a plurality of elastic pressing parts installed in a housing part to elastically support an outer side surface of the flow cell part;
• the plurality of elastic pressing parts are disposed in a longitudinal direction of the flow cell part;
• and each elastic pressing part comprises a pressing rod part,
• wherein the flow cell part includes:
• a flow cell body part in which the flow path is formed;
• a supply pipe part connected to one side of the flow cell body part so that the fluid medium is supplied to the flow cell body part;
• and
• a discharge pipe part connected to the other side of the flow cell body part so that the fluid medium is discharged from the flow cell body part,
• further comprising a bubble removal unit which is connected to a fluid medium inlet side of the flow cell part and removes bubbles mixed in the fluid medium introduced into the flow cell part,
• wherein the bubble removal unit includes:
• a bubble discharge line connected to the fluid medium inlet side of the flow cell part;
• and
• a bubble discharge valve installed on the bubble discharge line, and
• wherein one side of the bubble discharge line is connected to a circulation pump installed in a circulation flow path so that the bubbles of the bubble discharge line are discharged to the circulation flow path due to a suction pressure of the circulation pump,
• wherein a cross-section area of the flow cell body part is greater than a cross-section area of the supply pipe part so that the fluid medium forms a turbulent flow in the flow cell body part,
• wherein the supply pipe part includes:
• a first supply pipe part through which the fluid medium is supplied;
• and
• a second supply pipe part formed to have a diameter greater than a diameter of the first supply pipe part so that the fluid medium supplied through the first supply pipe part forms a turbulent flow,
• further comprising:
• a light source part and a photodetector part;
• further comprising:
• a first optical part installed to apply light applied from the light source part onto the fluid medium in the flow cell part;
• a second optical part installed to apply light, by which a wavelength of the fluid medium is absorbed while passing through the fluid medium in the flow path, to the photodetector part;
• and
• a third supply pipe part extending from the second supply pipe part and connected to the one side of the flow cell body part,
• wherein the third supply pipe part is connected to the flow cell body part so as to be inclined with respect to a longitudinal direction of the flow cell body part, and
• wherein the flow cell body part is disposed to be inclined upward from the supply pipe part side to the discharge pipe part side,
• further comprising:
• a first collimator part which faces the first optical part and to which a first optical fiber part is connected;
• and
• a second collimator part which faces the second optical part and to which a second optical fiber part is connected.
