Abstract
An on-line non-optical fiber fluorescent probe with light source and photoelectric sensor installed on probe features that the monochromatic light source and photoelectric converter are vertically installed in a tube made of opaque material, a narrow-band optical filter and a protecting glass are installed in front of said photoelectric converter, the upper and lower ends of said tube have liquid inlet and exhaust outlet, an optical cavity is formed in the middle, when the probe enters the solution to be detected, the solution to be detected enters the light absorption cavity from the liquid inlet, the monochromatic light emitted by the light source is absorbed by the solution to be detected in the light absorption cavity, the fluorescent substance in the solution emits fluorescence, the fluorescence passes through the protective glass and is filtered by the narrow-band filter, the fluorescence at the maximum emission wavelength of the fluorescent substance reaches the photoelectric conversion device, and the photoelectric conversion device converts the optical signal into an electrical signal to be output, thereby obtaining the fluorescence intensity at the maximum emission wavelength of the fluorescent substance in the solution to be detected.
Description
Affiliated technical field
The utility model designs the online non-optical fiber fluorescence probe that a kind of direct immersion detected solution is measured its fluorescence intensity.
Background technology
The used opticator of fluorophotometer generally is made of light source, beam splitting system, cuvette, optoelectronic sensor, its volume is bigger, environment for use is had relatively high expectations, operate comparatively loaded down with trivial details, can't be applied to require original position, online place, reach this purpose for addressing this problem common use fibre-optical probe, but fibre-optical probe complex manufacturing technology, cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of light source and optoelectronic induction device to enter the device that detected solution is measured fluorescence intensity of solution, this device has immersion at line structure, can be used for original position, on-line monitoring thus, have easy and simple to handle, with low cost, making characteristic of simple simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: monochromatic source and these two parts of electrooptical device are vertically mounted in the sleeve pipe of a light-proof material making mutually; fluorescence narrow band pass filter and cover glass are installed on the electrooptical device receiving plane, are made a probe that can enter detected solution.Probe leaves inlet and exhausr port, the middle extinction chamber that forms; When probe enters detected solution, detected solution enters the extinction chamber from inlet, after the detected solution of the monochromatic light that is sent by light source in the extinction chamber absorbs, the fluorescence that fluorescent material is launched in the solution is through the filtration of optical filter, the light of maximum emission wavelength arrives electrooptical device by optical filter, electrooptical device is converted to electric signal output with light signal, obtain the fluorescence intensity of detected solution (equals the wavelength of monochromatic source) under excitation wavelength emission wavelength (equaling the centre wavelength of optical filter) thus, select for use the fluorescent probe that corresponding excitation/emission wavelength light source and optical filter are housed to measure different fluorescence systems.
The beneficial effects of the utility model are; owing to use the online design of immersion, only need during mensuration probe is immersed detected solution, do not need lucifuge; cancelled the design of common photometric cuvette; therefore simple to operate, also can satisfy original position, on-line analysis requirement, the utility model is by monochromatic source in addition; cover glass and narrow band pass filter; electrooptical device and extinction cavity segment are formed, and be simple in structure, therefore simple for production, with low cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model cross-sectional view
Among the figure: 1. light tight shell, 2. electrooptical device, 3. monochromatic source, 4. narrow band pass filter, 5 cover glasses, 6. extinction chamber, 7. inlet, 8. exhausr port, 9. light source power line, 10. signal wire.
Embodiment
As shown in Figure 1: light source power line (9) on will popping one's head in and signal wire (10); difference energized and D/A converting circuit; to pop one's head in and immerse detected solution to exhausr port fully and be submerged fully; solution enters the extinction chamber from inlet (7); after the detected solution of the monochromatic light that is sent by monochromatic source (3) in extinction chamber (6) absorbs; fluorescent material in the solution sends fluorescence; fluorescence sees through cover glass (5); after narrow band pass filter (4) filters; the fluorescence that is positioned at maximum emission wavelength of fluorescent material arrives electrooptical device (2); electrooptical device is converted to electric signal with light signal and outputs to the digital-to-analog conversion device through signal wire (10), obtains the fluorescence intensity of detected solution thus.Inlet (7) wherein, exhausr port (8) size is suitable, too greatly then can cause surround lighting to enter the extinction chamber, and influence is measured, the too little solution that then can influence enters extinction chamber speed, owing to this probing shell is made of light tight macromolecular material, so do not need the lucifuge operation.
Claims (4)
1. an online non-optical fiber fluorescence is popped one's head in; it is characterized in that: light source and optoelectronic induction device are housed in light tight shell; narrow band pass filter and cover glass are housed before the electrooptical device, inlet and exhausr port are arranged, the middle extinction chamber that is full of by solution that forms at the shell two ends.
2. online non-optical fiber fluorescence probe according to claim 1, it is characterized in that: light source and electrooptical device are installed in the incorporate non-fibre-optical probe of the indoor formation of light-proof material light, and whole probe immersion detected solution is measured during work.
