Description
Technical field
The utility model relates to a kind of spectrophotometer apparatus, particularly relates to the portable spectrophotometer of microcapsules.
Background technology
Ultraviolet-visible spectrophotometer is that one makes ght transmission sample, analyzes its absorption spectrum and instrument that is qualitative to composition or quantitative test.Generally be made up of light source, monochromator, sample cell and detecting device.Traditional ultraviolet-visible spectrophotometer product, use the 10mm light path liquid sample pool of standard, testing liquid consumption is generally more than 2mL.When for life science, when particularly measuring albumen, DNA and RNA content, sample is generally precious, and relative concentration is higher, thus must first dilute when using 10mm sample cell.Dilution consumes solvent, complex operation, and after dilution, sample cannot be recycled.There is the spectrophotometer in the submicrosample pond for this application in recent years, directly can carry out photometric analysis to micro updating sample.The luminosity pond of most of micro photometer on the market, is generally made up of two glass with certain interval (general 0.2mm, 0.5mm or 1mm) or quartzy plane.During measurement, two planes separately, micro-drop is dropped in the ad-hoc location (conventional hydrophobic surface or miniature concave surface fix liquid) in one of them plane, plane of then closing, drop is formed thin layer or the miniature cylinder with specific thicknesses by two plane extruding.After two glass planars, be provided with two optical fiber mutually aimed at, source light, from a fiber exit, through glass, then through liquid lamella, then through glass planar, enters detection fiber.The detection fiber other end is connected to monochromator and photoelectric commutator, to analyze the absorption spectrum of liquid.
In some design, a glass planar can replace with minute surface, and transmitting and detection fiber are arranged on homonymy, and light is through mirror-reflection, and secondary, through glass and liquid, enters reception optical fiber.Because light passes twice through liquid, equivalent optical path doubles, and mechanism's actual gap can be made thinner, and consumable liquid is less.In said method, all need a machinery folding mechanism, closed later plane distance is measurement light path, the mechanical register pin of general dependence or locating surface ensure this distance, closing action from opening to, if mechanical register pin or locating surface wear and tear, mix dust or liquid, can positioning precision be affected, and then affect light path, cause measuring error.Fluid drips is on glass or quartzy face on the other hand, and after having measured, need manual by drop erasing, this can bring series of problems: manual wipping slow motion, cannot realize high flux and automatic measurement; The wrong difference of people's manual manipulation, easily erasing is unclean, and particularly protide sample has stronger adhesiveness, easily remains in glass surface, affects absorbance measuring, and pollutes the sample next time instilled; Long-term wipe surfaces, surface abrasion becomes flower, and not only optical property worsens, and hydrophobicity and Adhesion Resistance all can decline, and need periodic maintenance otherwise affect instrument performance.The utility model patent of prior art as Authorization Notice No. CN 102435569 B discloses a kind of micro photometer and comprises micro-luminosity pond, front supporting member, rear support, front rolling wheel, back winding wheel, point sample mechanism; The plastic film tape be wrapped on described front rolling wheel is connected with described back winding wheel by described front supporting member, described point sample mechanism, described micro-luminosity pond, described rear support successively.The micro photometer that this utility model provides, can realize the high flux screening of sample, can automatically run without the need to manual maintenance, only need regular replenishment film strip.But in marine monitoring, jiggly cabin is often one of unavoidable mal-condition of test environment, and prior art cannot overcome this drawback, has impact unavoidably on experiment.
Summary of the invention
The purpose of this utility model be for prior art provide a kind of test easy, complex environment can be adapted to, be easy to microminiaturized and manufacture, the portable spectrophotometer of microcapsules that testing process manual intervention is few.
The utility model solves the problems of the technologies described above adopted technical scheme: the portable spectrophotometer of microcapsules, comprise the reel being wound with detector bar, detector bar part through the traction of positioning roller and traction rollers, wherein: near the part detector bar of positioning roller and traction rollers, be provided with filling gun and photodetector; Detector bar is capsule bar; Capsule bar is made up of base plate and the capsule chamber binded on this base plate.Need independently chemical reagent to be housed in advance according to detection in capsule chamber, by solution injection filling gun to be detected during detection, reacted in injection of solution to be detected to capsule chamber by filling gun, and after detect through photodetector.
For optimizing technique scheme, the measure taked also comprises: be provided with filling gun and photodetector near the part detector bar of positioning roller and traction rollers; Detector bar is capsule bar; Capsule bar is made up of base plate and the capsule chamber binded on this base plate.Need independently chemical reagent to be housed in advance according to detection in capsule chamber, by solution injection filling gun to be detected during detection, reacted in injection of solution to be detected to capsule chamber by filling gun, and after detect through photodetector.Capsule chamber top also has the coping plate substantially parallel with base plate.Preferably adding a slice coping plate to improve precision capsule chamber top, making light path in the solution of measurement basically identical.Photodetector light path is provided with the glass clamping device that can clamp capsule bar near capsule bar place.Glass clamping device is adopted to be the means can stablizing light path equally.Whether adopt preferred version, will determine according to measuring accuracy, lower for precision, because the specification of capsule bar is less, its light path can basic task be consistent, adopts the base plate of one side.Along with the raising that accuracy of detection requires, more high-precision scheme can be selected.Photodetector, as detection components, with reference to relevant prior art, can not repeat them here.
Filling gun and photodetector is provided with due near the part detector bar that the utility model have employed positioning roller and traction rollers; Detector bar is capsule bar; Capsule bar is made up of base plate and the capsule chamber binded on this base plate.Need independently chemical reagent to be housed in advance according to detection in capsule chamber, by solution injection filling gun to be detected during detection, reacted in injection of solution to be detected to capsule chamber by filling gun, and after detect through photodetector.Thus the utility model have test easy, complex environment can be adapted to, be easy to microminiaturized and manufacture, advantage that testing process manual intervention is few.
