Description
Technical field
The utility model relates to a kind of absorbance detection device being applied to analysis meter, and in particular, the utility model relates to a kind of absorbance detection device with reagent mixing constant-temperature dehumidifying function.
Background technology
Absorbance detection device adopts optical method to carry out the vitals of matter concentration measuring instrument, existing absorbance detection device, just simply arranges light source and optical receiver in cuvette both sides, carries out absorbance measurement to detected solution.Mainly there is following problem in this pick-up unit.
1) because light source and detecting device are arranged on cuvette both sides, in testing process, the temperature impact of reactant liquor in cuvette can be subject to, also easily be subject to the impact of variation of ambient temperature.The temperature variation of light source can cause determined wavelength to drift about, and the temperature variation of detecting device can cause the technical parameter of electronic original part to fluctuate, and these changes are all by the accuracy of impact detection.
2) when solution temperature to be measured is lower than environment temperature, and cuvette ambient humidity, light and temperature larger time, the solution to be measured of injection can cause occurring fog around cuvette, and time serious, cuvette outer wall there will be condensation, this situation by the detection of interference absorbance, and easily produces corrosion to electronic original part.
3) existing absorbance detection device needs manually reagent and sample to be mixed, solution could be injected cuvette after having reacted, carry out in the colour developing of sample and the no longer same device of detection, not only increase the workload of testing staff, and solution may be polluted in transfer process, the accuracy of detection and stability is caused to reduce.
4) some thermally sensitive chromogenic reaction, after being injected into cuvette, the colour developing process of solution by influenced by ambient temperature, and then can reduce the accuracy of detection.
Summary of the invention
Problem to be solved in the utility model, overcomes the defect of above-mentioned prior art exactly, and provides a kind of absorbance detection device with reagent mixing constant-temperature dehumidifying function for this reason.
The technical solution of the utility model is as follows:
A kind of absorbance checking device with reagent mixing constant-temperature dehumidifying function, comprise the fore shell for locating cuvette and back seat, in fore shell, arrange LED light source and drying agent, drying agent uses the foraminate fore shell cover plate encapsulation of band, arranges well heater and optical receiver in back seat.Heating resistor and temperature sensor is inlayed in well heater.Optical receiver uses back seat cover plate for sealing.Heat-conducting silica gel sheet is placed between cuvette and well heater.Described fore shell and back seat fasten mutually, place cuvette between.The upper and lower of cuvette arranges outlet respectively and is connected with mixing pump.
The utility model, compared to prior art, has following beneficial effect:
1) make because fore shell and back seat are heatpiston, high insulating effect, ensure that pick-up unit internal temperature is not influenced by ambient temperature;
2) because light source and receiver are sealed in device inside by fore shell and back seat, light path can not receive contamination by dust, and moisture also can not be made to enter;
3) make device inner sealing because fore shell and back seat fasten mutually, and fore shell inside arranges drying agent, absorb the moisture in pick-up unit, reduce the humidity of pick-up unit inside, also can not produce fog when solution temperature to be measured is lower;
4) owing to being provided with soft heat-conducting silica gel sheet between cuvette and well heater, extrude the air between well heater and cuvette, be more conducive to the conduction of heat.Heat-conducting silica gel sheet has cushioned the change in size that cuvette produces when expanding with heat and contract with cold, and avoids cuvette and damages;
5) because heating resistor and temperature sensor are set together, temperature-responsive speed is fast, and heated at constant temperature is effective.
6) owing to being provided with mixing pump, can by reagent and solution rapid mixing to be measured, reaction and the detection of solution to be measured complete at same position, eliminate the disturbing factor produced in solution transfer process to be measured.
