Abstract
The utility model provides a UV detection mechanism, which comprises an explosion-proof cabinet, a detector, an optical fiber, a circulating tank unit and a liquid path tube. The optical fiber is connected with the detector, and the liquid path tube passes the circulating tank unit. The UV detection mechanism is characterized in that the detector is arranged inside the explosion-proof cabinet, the circulating tank unit and the liquid path tube are positioned outside the explosion-proof cabinet, and the optical fiber is connected between the detector and the circulating tank unit. The UV detection mechanism has the advantages that utilization and safety of the explosion-proof cabinet can not be affected even in case of leakage due to the fact that the liquid path tube does not pass the explosion-proof cabinet and the circulating tank unit is arranged separately from an optical unit.
Description
[technical field]
The utility model relates to a kind of UV testing agency, relates in particular to the UV testing agency in a kind of preparation of industrialization liquid chromatographic system.
[background technology]
Detecting device is the topmost unit instrument in the preparation of industrialization liquid chromatographic system.Effectively detect is the necessary condition that realizes one matter purifying, chromatography.The preparation of industrialization liquid chromatographic system generally is applied to occasions such as chemical industry is synthetic, bio-pharmaceuticals, requires very high to explosive-proof grade.
Common UV detecting device is that the flow cell by liquid is close on the optical unit body, realizes effectively instant the detection with short light path.But this UV detector approach has limited the environmental applications that liquid chromatographic system is being had relatively high expectations to explosive-proof grade.
In order to satisfy high-grade requirement of explosion proof, some producer together is enclosed in one section influidic pipe of detecting device and connection detector in the explosion-proof cabinet, and still, so easy generation influidic pipe is revealed and is difficult to found potential danger.
In view of the above problems, be necessary to provide a kind of new UV testing agency to solve the problems referred to above.
[utility model content]
The technical matters that the utility model solved is to provide a kind of UV testing agency, and it can ensure the safe handling of explosion-proof cabinet.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of UV testing agency, comprise that explosion-proof cabinet, detector, the light transmitting fiber that links to each other with described detector, flow cell unit reach the influidic pipe by described flow cell unit, described detector is located in the described explosion-proof cabinet, described flow cell unit and influidic pipe are positioned at outside the described explosion-proof cabinet, are connected with light transmitting fiber between described detector and the described flow cell unit.
Further, described detector is provided with optical unit body, and described light transmitting fiber one end is connected with described optical unit body.
Compared to prior art, UV described in the utility model testing agency is by with the separate setting of flow cell unit with optical unit body, even if make that influidic pipe has leakage also can not have influence on the use and the safety of explosion-proof cabinet.
[description of drawings]
Fig. 1 is the structural representation of UV described in the utility model testing agency.
[embodiment]
See also shown in Figure 1, the utility model provides a kind of UV testing agency 10, and it comprises explosion-proof cabinet 1, be located at detector 2 in the explosion-proof cabinet, link to each other with described detector 2 and extend the light transmitting fiber 3 of described explosion-proof cabinet, the influidic pipe 5 of being located at the outer flow cell unit of described explosion-proof cabinet 4 and passing through described flow cell unit 4.
Described explosion-proof cabinet 1 is a square housing, is provided with the container cavity of accommodating described detector 2 in it.
Described detector 2 places in the described container cavity and comprises an optical unit body 6, and this optical unit body 6 is used to detect described liquid.
Described light transmitting fiber 3 passes the perisporium of described explosion-proof cabinet 1, and seals in the exit of passing perisporium.The two ends of this light transmitting fiber 3 connect the optical unit body 6 on flow cell unit 4 and the detector 2 respectively, realize remote detection.
That described flow cell unit 4 is placed on described explosion-proof cabinet 1 is outer and carry out remote detection with light transmitting fiber 3 joint detection instrument 2, has realized separating of flow cell unit 4 and optical unit body 6 thus, has also reached dead-tight effectively explosion-proof.
Described influidic pipe 5 passed described flow cell unit 4, and without described explosion-proof cabinet 1, therefore, even the use and the safety that also can not have influence on explosion-proof cabinet 1 takes place to reveal in this influidic pipe 5.
The above only is a most preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art are not breaking away under the technical solutions of the utility model scope situation, utilize the method content of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, all belong to the scope of claims protection.
Claims (2)
1. UV testing agency, comprise that explosion-proof cabinet, detector, the light transmitting fiber that links to each other with described detector, flow cell unit reach the influidic pipe by described flow cell unit, it is characterized in that: described detector is located in the described explosion-proof cabinet, described flow cell unit and influidic pipe are positioned at outside the described explosion-proof cabinet, are connected with light transmitting fiber between described detector and the described flow cell unit.
2. UV according to claim 1 testing agency, it is characterized in that: described detector is provided with optical unit body, and described light transmitting fiber one end is connected with described optical unit body.
