Abstract
The utility model discloses a flow-injection photometric micro-sensor analyzer which comprises a reagent pump, a sample pump, a reaction, a results display and a photometric micro-sensor; the reagent pump and the sample pump are respectively connected with the flow-injection system which is composed of the reactions, and the photometric micro-sensor is connected with the reactions and the results display. Each of the reagent and the sample pump uses a trace peristaltic pump. The analyzer can test the chemical composition in a sample (such as formaldehyde); by photometric micro-sensor with the strong identification for the chemical composition, the analyzer can quickly test whether a sample comprises a chemical composition and content. The establishment of a micro-flow injection sampling system can provide the automatic sampling and the automatic display of the test result, and can accelerate the speed of test.
Description
Technical field
The utility model relates to a kind of photometric analyzer, and the particularly a kind of flow injection luminosity micro sensing analyser that can test fast has purposes very widely in analysis fields such as chemistry, biology, medicine, material.
Background technology
In order to measure the content of certain material composition, can use colorimetric analysis.Photoelectric colorimetry is used very wide in fields such as chemistry, medicine, biology, investigations of materials, its principle is exactly the particular color that utilizes test substance and developer reaction back to be produced, and determines its content with its transmittance of measurement after the monochromatic light transmission.In traditional photoelectro-colorimetric analysis instrument, require with halogen light source and heat abstractor thereof, also have a whole set of to light beam focus on, the optical system of collimation, beam split; And, for fear of the interference of surround lighting, also whole test section must be hidden.Like this, the optical system of instrument and test section volume just seem very big.In addition, experimentation needs manual operations, and is comparatively time-consuming.Therefore, adopt the instrument of traditional structure to want to reduce volume or improve its automaticity all to be restricted.
The utility model content
Technical problem to be solved in the utility model is: a kind of flow injection luminosity micro sensing analyser is provided, can tests fast sample, and simple to operate, easy to carry.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flow injection luminosity micro sensing analyser, it comprises reagent pump, sample pump, reaction tube and display screen and luminosity microsensor as a result, described reagent pump and sample pump are connected to described reaction tube respectively and form the flow injection system, and described luminosity microsensor is connected to described reaction tube and described display screen as a result.
Further improvement in the technical proposal is: described reagent pump and sample pump all adopt micro-peristaltic pump, have adopted the pick-up unit of luminosity microsensor as analysans.
Flow injection luminosity micro sensing analyser of the present utility model has the following advantages: described analyser can detect a certain chemical analysis in the sample (for example formaldehyde), by adopting the luminosity microsensor that described chemical analysis is had strong recognition capability, whether contain this chemical analysis and content and can fast detecting go out sample.And set up micro-flow injection sampling system, and can realize the robotization of sample collecting and the automatic demonstration of test result, accelerated detection speed.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model flow injection luminosity micro sensing analyser.
Embodiment
Please refer to Fig. 1, the utility model flow injection luminosity micro sensing analyser comprises a reagent pump 10, a sample pump 20, a reaction tube 30, a luminosity microsensor 40 and a display screen 50 (for display screen as a result) as a result, described reagent pump 10 and sample pump 20 are connected to described reaction tube 30 respectively and form a mobile injecting systems, described reaction tube 30 is connected to described luminosity microsensor 40, and described display screen as a result 50 also is connected to described luminosity microsensor 40.Manage in the described luminosity microsensor and be M shape, its turning point is an arc transition.
When testing with this tester, sample to be measured is conveyed into described reaction tube 30 by described sample pump 20, select suitable reagent according to the chemical analysis that will detect, described reagent is conveyed into described reaction tube 30 by described reagent pump 10, chemical reaction takes place in described sample and reagent in described reaction tube 30, product behind the chemical reaction is by described luminosity microsensor 40 inductions, and the result that will sense shows on described display screen as a result 50, thereby can learn whether contain described chemical analysis (for example formaldehyde) and content thereof in the sample.
In the utility model, described reagent pump 10 and sample pump 20 have all adopted the micro-peristaltic pump of low-voltage (6～7v rechargable battery), miniwatt (3w), and this pump has the advantages that volume is little, in light weight, power consumption is few.Have analog to digital conversion circuit, control circuit and automatic display unit in the display screen 50 as a result.
The utility model has been set up micro-flow injection sampling system, has realized the robotization of sample collecting and the automatic demonstration of test result, has accelerated detection speed.And realized the microminiaturization of instrument, be convenient for carrying.The whole instrument volume is about the instrument volume and is about 250 (L) * 180 (W) * 250 (H) mm, and weight is less than 2kg.Detection speed is 1 sample/per minute, is limited to 1ppm under detecting.
Described flow injection luminosity micro sensing analyser detection speed is fast, need not cuvette, and collected specimens is simple to operation automatically, does not need the curve of working, and shows automatically testing result to be suitable for fast measuring; And reagent consumption is extremely low, and it only is 100 μ l that every sample consumes reagent, significantly reduces secondary pollution; Volume is little, and exterior design is attractive in appearance, reasonable, and embedded carrying handle is arranged, and is easy to carry, by using different reagent instead, and can detect different chemical analysis.
