Abstract
The utility model relates to a flow cell for sensing film fluorescence analysis, which solves the defect that a light path of the prior art has poor stability. The utility model comprises a cell body, a bolt, a sealing washer, a sensing film, etc., wherein both sides of the cell body are provided with screw holes in which opening screws are fixed, plastic pipes are fixed in the opening screws, the top ends of the plastic pipes are provided with the sealing washer, the upper end of the cell body is provided with an opening bolt in which the common end of furcation optical fibers is arranged; the sensing film is arranged in a sensing film fixing groove, and the sensing film is fixed and pushed in the sensing film fixing groove by a fixing bolt from the lower part of the cell body; the sealing washer is arranged between the fixing bolt and the sensing film. The light path of the utility model has the advantages of excellent stability and good sealing performance so that the utility model avoids the leakage of liquid, and meanwhile, the sensing film is convenient to clean and replace; the cell body made of nontransparent materials forms a light shading system so that the utility model eliminates the interference of environmental stray light, reduces the pollution of dust and impurities in air to the sensing film and extends the service life of the sensing film.
Description
Technical field:
The utility model relates to a kind of test chemical apparatus for conducting assay, particularly relates to a kind of sensing membrane fluorescence analysis flow cell.
Background technology:
Fluorescent optical fiber sensor is the big hot topic research field when front sensor, and the manufacturing of probe is the key of sensor.General fluorescent optical fiber sensor often adopts the static analysis probe.Both arms optical fiber common port is inserted in the probe, sensing membrane is fixed on the glass substrate, be fixed in Chi Tizhong with securing member, common port over against bifurcation fiber, during test, whole probe is immersed sample solution, import probe into after the one arm coupling of the light of light source and bifurcation fiber, be radiated on the sensing membrane, be embedded in indicator in the film generation fluorescence that is excited, the sample and the indicator that flow into probe by sample intake passage produce certain reaction, cause the variation of its fluorescence, and this signal is passed detecting device back by another arm of bifurcation fiber.Because the normal bonding agent that adopts is connected and fixed between optical fiber and the probe, use back several times is loosening easily; Sensing membrane needs attached on the transparent glass substrate in addition, and background stray light also can be passed through, and therefore this static analysis probe often exists stability of layout relatively poor, is subject to shortcomings such as extraneous interference of stray light.
The utility model content:
The utility model has solved the above-mentioned defective of existing in prior technology, provides a kind of stability of layout good mobile sensing membrane fluorescence analysis flow cell.
The technical solution of the utility model is as follows: it comprises pond body and set bolt two parts; It is characterized in that: body both sides, pond have screw, screw in the screw that has center pit, and to place the plastic tube as feed pathway and liquid outlet channel, the plastic tube top adds packing washer; The tapping bolt of center pit is opened in pond body upper end processing one, with bifurcation fiber common port threads engaged, in order to fixed fiber; Set bolt is connected threadably with the pond body, and sensing membrane places in the square groove that pond body one holds successfully, adorns a packing washer between set bolt and sensing membrane, screw in set bolt then sensing membrane be crushed in the square groove.
The utility model is compared with the static probe device, has the following advantages:
1. with the thread forms fixed fiber, the stability of layout excellence;
2. with thread forms fixedly feed liquor, fluid plastic tube and pressure-sensitive diaphragm, and add sealing filler ring, avoided the leakage of liquid, also conveniently simultaneously clean, change pressure-sensitive diaphragm;
3. the pond body made from opaque material has formed the lucifuge system, has eliminated the interference of extraneous parasitic light, has reduced also that dust and impurity have prolonged the serviceable life of sensing membrane to the pollution of sensing membrane in the air.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Label declaration: 1. bifurcation fiber, 2. pond body, 3. plastic tube, 4. packing washer, 5. sensing membrane, 6. set bolt, 7. tapping bolt, 8. tapping bolt.
Embodiment:
As shown in Figure 1, the utility model comprises pond body and set bolt two parts.Pond body (2) both sides have screw, screw in the screw (7) that has center pit, and to place the plastic tube (3) as inlet opening and fluid hole, plastic tube (3) top adds packing washer (4).The tapping bolt (8) of center pit is opened in pond body (2) upper end processing one, with bifurcation fiber (1) common port threads engaged, in order to fixed fiber.Set bolt (6) is connected threadably with pond body (2), sensing membrane (5) places in the square groove that pond body (2) holds successfully, adorn a packing washer (4) between set bolt (6) and sensing membrane (5), screw-in set bolt (6) then sensing membrane (5) is crushed in the square groove.
After the bifurcation fiber common port is fixed in the tapping bolt (8), a certain wavelength exciting light from light source enters the pond body from bifurcation fiber (1) one arm, shine on sensing membrane (5), be embedded in fluorescent dye in the film generation fluorescence that is excited, certain density determinand solution is pumped to Chi Tizhong and contacts with sensing membrane, caused the variation of sensing membrane fluorescence intensity, this signal transfers to detecting device by another arm of bifurcation fiber (1), thereby has realized the purpose of this utility model.
Big I of the present utility model is made as required, and material adopts resistance to chemical attack and the good teflon of weatherability.
