Description
Technical field
The utility model relates to a kind of optical detection apparatus, the optical detection apparatus that especially convection cell detects.
Background technology
In the existing detection technique in market, colorimetric pool is as one of most crucial parts, conventionally only has a surveyed area, materials different in fluid is different to the absorption of the light of different wave length, therefore the method that detects this material is in colorimetric pool, to walk certain distance (being light path) with the detection light that it the most easily absorbs, by measuring by the intensity of the particular detection light of colorimetric pool from the other end, calculate colorimetric pool inner fluid to the consumption of light intensity (being light loss), and then calculate the concentration of this material of colorimetric pool inner fluid.
Situation 1: when the specific substance concentration in colorimetric pool surpasses certain value, detecting light will be completely consumed, the other end just cannot measure detection light, it is how many no matter concentration surpasses definite value degree, the light loss that detection computations goes out is all that definite value, its material concentration calculating is also a definite value, and cannot calculate concentration actual value, is how many.
Situation 2: when certain material concentration of colorimetric pool inner fluid is very little, the light loss that detects light is also very little.Because it is constant to measure the error of detection light device, when the light loss that detects light and error amount ratio are over certain proportion or light loss during lower than error, detection material concentration value, accuracy and the repeatability that now meter is calculated will exceed standard or measured value is negative, usually said inaccurate or unstable.
Situation 1 is exactly the upper limit of detection of often saying, situation 2 is exactly the lower limit that detects of often saying.The method that improves detection lower limit normally increases light path increases light loss, but light path is constant, by colorimetric pool size, is determined, has in fact reduced the upper limit of detection of colorimetric pool when having increased light path, thereby cannot take into account upper limit of detection simultaneously and detect lower limit.The method that both take into account is normally diluted test fluid, but dilution action is normally judged what detection material concentration just started when reaching or approaching higher limit in system, again detects, and therefore expends time in, reagent is all double, and some reagent cost is high, or containing severe toxicity.
Summary of the invention
In order to overcome the problems referred to above, many light paths detection cell that the utility model provides is simple to operate, upper limit of detection is different with lower limit.
The technical solution of the utility model is to provide a kind of many light paths detection cell, and it comprises the colorimetric pool of hollow, is provided with import and outlet on described colorimetric pool, it is characterized in that: described colorimetric pool comprises the detection zone that a plurality of light paths differ.
Preferably, described colorimetric pool is columnar structured, its both ends open, one end is described import, the other end is described outlet, and described colorimetric pool middle part arranges at least two columnar structured described detection zones that diameter is different, and described detection zone is coaxial with described colorimetric pool.
Preferably, described colorimetric pool middle part arranges two described detection zones, and the connecting pipe that described export and import is respectively less than described detection zone diameter by a diameter is communicated with described detection zone.
Preferably, detection zone is arranged in parallel described in the cylindrical shape of several closed at both ends, jointly forms described colorimetric pool, between described detection zone, is interconnected, and the length of whole described detection zones is all not identical.
Preferably, described colorimetric pool is integrally formed by quartz glass.
Preferably, by height, thoroughly to mould glue integrally formed for described colorimetric pool.
Many light paths detection cell of the present utility model changes the defect that traditional detection pond only has a detection zone, and design has the structure of a plurality of detection zones, is not increasing under the prerequisite of too much detection liquid, obtains a plurality of different upper limit of detection and lower limit.Many light paths detection cell of the present utility model has simple in structure, a plurality of different upper limit of detection and lower limit, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model the first embodiment;
Fig. 2 is the sectional structure schematic diagram of the utility model the second embodiment.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of many light paths detection cell of the utility model the first embodiment comprises columnar structured colorimetric pool 10, its both ends open, and one end is import 12, the other end is outlet 14, for detecting liquid turnover.
Colorimetric pool 10 middle parts arrange two columnar structured detection zones 16 and 18 that diameter is different, and detection zone 16,18 is coaxial with colorimetric pool 10.Outlet 14 and import 12 are respectively less than connecting pipe 20, the 22 communication with detection districts 16,18 of detection zone diameter by a diameter.During detection, detect the detection zone 16,18 that light can be selected different-diameter as required, from radially irradiating, realize and detecting, its corresponding light path is different, thereby obtains different upper limit of detection and lower limit, has arrived the object of detection.
As shown in Figure 2, in the utility model the second embodiment, adopt the cylindrical shape detection zone 24,26,28 of several closed at both ends to be arranged in parallel, jointly form colorimetric pool 10, between detection zone 24,26,28, be interconnected.During use, one end of light source (not shown) detection zone is shining into, and the other end detects, and because the length of detection zone differs, thereby obtains the light path of different length.
Further, by common quartz glass or height, thoroughly to mould glue integrally formed for colorimetric pool 10.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
