Abstract
A fluid medium monitoring apparatus of the present invention comprises: a light source unit for irradiating light; a first collimator unit for collimating light irradiated from the light source unit; a flow cell unit in which a fluid medium flows and light is allowed to absorb the wavelength of the fluid medium while proceeding along the moving direction of the fluid medium; and a light detection unit for detecting the wavelength of the light passing through the flow cell unit.
Claims12
A fluid medium monitoring apparatus comprising:
- a light source configured to apply ultraviolet rays;
- a first collimator configured to align the ultraviolet rays applied from the light source as parallel rays;
- a flow cell in which a fluid medium in a liquid state flows and ultraviolet rays is allowed to absorb a wavelength of the fluid medium while proceeding in a moving direction of the fluid medium;
- and
- a light detector configured to detect a plurality of wavelengths of the ultraviolet rays passing through the flow cell,
- wherein the light detector includes:
- a second collimator configured to collect the ultraviolet rays passing through the flow cell;
- a charged-coupled device (CCD) configured to detect the plurality of wavelengths of ultraviolet rays passing through the second collimator;
- and
- a noise reducer including a cooling element disposed on the light detector with the cooling element being configured to reduce noise of the light detector by cooling the light detector,
- wherein the fluid medium monitoring apparatus further includes:
- a first optical fiber connected to the light source and the first collimator to form an optical path so that the ultraviolet rays applied from the light source is applied to the first collimator;
- and
- a second optical fiber configured to form an optical path so that ultraviolet rays applied through the flow cell is applied to the light detector, and
- wherein the light source includes:
- a light-emitting lamp configured to apply ultraviolet rays;
- and
- a convex lens configured to collect the ultraviolet rays applied from the light-emitting lamp.
