Abstract
The utility model relates to a stirring measuring device, which is mainly applied to the field of electrochemistry analysis. The device adopts direct current power supply, the rotting speed is stable, in addition, the whole process is completely controlled by a computer, the stirring, and the cleaning and the measurement of an electrolytic cell can be controlled through the computer, so the measuring process is simple, and measuring results are reliable. Simultaneously, the minimum design is carried out on the whole device, so the device has a simple and compact structure. Therefore, the device has the advantages that the size is small, the carrying is convenient, the automation degree is high, and the operation is easy.
Description
Technical field
The utility model relates to a kind of stirring measurement mechanism, is particularly useful for the detection of metal ion content in the water analysis, belongs to the electrochemical analysis field.
Background technology
The electrochemical analysis technology is widely used in also being applied in the detection of solid phase extraction liquid ions content in the metal ion detection of environment water.At present, electrochemical analysis is measured generally by using magnetic stirrer and electrolysis to realize the stirring and the measurement of solution to be measured, this stirring and measuring process all need manual control, and generally adopt Alternating Current Power Supply, cause easily because the stirring rate that voltage instability brings is inhomogeneous, therefore make that instrumentation is loaded down with trivial details, measurement result is inaccurate.
The utility model content
The utility model provides a kind of stirring measurement mechanism, is used for the electrochemical analytical instrument field.This device adopts direct current supply, stabilization of speed, and whole process is stirring, cleaning and the measurement of may command electrolytic cell fully by computer control by computer, makes measuring process simple, measurement result is reliable.Simultaneously, whole device is carried out miniaturized design, made this apparatus structure simple, compact.Therefore this device have volume little, be easy to carry, the advantage of automaticity height, easy operating.
This stirring measurement mechanism partly is made of solution cup, solution cup, puddler, electrode, motor, outer cover, electrode body, capping etc.Motor is fixed on the electrode body, connect on the central shaft of motor puddler and with the puddler interference fit, the motor high speed rotating drives puddler with the speed rotation.Electrode inserts the mounting hole of electrode body, can comprise several electrodes of needs when measuring in the mounting hole simultaneously.On the electrode body and leave air hole and injection port, thereby make things convenient for the deoxygenation and the sample introduction of sample solution.
Stirring measurement mechanism described in the utility model, concrete using method is: pour solution to be measured into the solution cup, plug electrode, starter motor begins to stir and measure.
Description of drawings
Fig. 1 is a stirring measurement mechanism structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
As Fig. 1, motor (3) is fixed among the electrode body (2), connect puddler (5) on the central shaft of motor, electrode (4) inserts the mounting hole of electrode body, cover upper cover (1), integral body mounts on solution cup (7) then, and puddler and electrode have and stretch in the solution cup and be immersed in sufficient length in the solution.Wherein, solution cup (7) is fixed on the solution cup (8), and outer cover on the cup outer cover (6), outer cover are transparent, is convenient to observe.
Before the measurement, in software, set each experiment parameter earlier.Survey blank solution (distilled water) and solution to be measured during measurement earlier, in solution to be measured, add standard model then and measure.After measurement finishes, by solution to be measured with add the current curve (deduction is blank) that the current curve of solution behind the standard sample respectively deducts blank solution, can accurately try to achieve solution metal ion concentration to be measured by the standard increment method then.The standard increment method is meant: the standard solution of a certain amount of concentration known is added in the testing sample, measure the concentration of sample before and after adding.Concentration behind the adding standard solution will be than the height before adding, the amount of contained test substance in the standard solution that the amount of its increase should equal to add.If there is interfering material in the sample, then the added value of concentration will less than or greater than theoretical value.
Claims (4)
1. stirring measurement mechanism, comprise parts such as solution cup, solution cup, puddler, electrode, motor, outer cover, electrode body, capping, it is characterized in that: adopt direct current supply, motor is fixed among the electrode body, and puddler is directly stirred by driven by motor; Stir, clean and measure by the omnidistance control of computer.
