The polymer capillary has diameter of 0.1-1 mm and is easy to replace and control. The present invention is used in research, analysis and detection in material science and technology.
Description
Technical field the present invention relates to a kind of microscopic electrochemical analyzer, particularly relates to working electrode, contrast electrode and auxiliary electrode control and the device of analyzing.
This complete equipment of background technology microscopic electrochemical is applied to measure out of phase electrochemical activity in the material, in the welding process, the corrosivity of weld interface zones of different, and different electrochemical activity between crystal grain and the crystal boundary, can improve the constituent of material by the research of these aspects, processing technology, thereby the corrosion resistance of raising material.What use when this class problem of research at present is to contact as working electrode with sample with the solution in the glass capillary, because glass tube can be thrown 1mm, so very effective for tiny area, but for the bigger zone of test the time, it has shown its limitation.The most advanced and sophisticated position of glass tube is very easily damaged, glass tube tip need be controlled contacting of solution and sample with the silica gel sealing edge, in addition, contrast electrode and working electrode, auxiliary electrode is not in a zone, so just caused to have the bubble generation between them, thereby influenced the operation in whole loop.At this situation, this product has proposed the kapillary that adopts macromolecular material to make to this technological experiment, and working electrode, contrast electrode and auxiliary electrode are integrated on the device.Thereby reach fast, simple, advantage such as workable.
Summary of the invention the objective of the invention is to provide a kind of can be quick, simple, a workable cover microscopic electrochemical analyzer.Electrochemical analyser provided by the invention is made up of 3 major parts: the microscopic electrochemical proving installation; Data handling system; And utility appliance.The microscopic electrochemical proving installation is comprising optical microscope, (it is contacted as working electrode with sample by the solution of the kapillary loading that macromolecular material is made the electrode integrating device, platinum filament or spun gold are as auxiliary electrode, and small Ag/AgCl or saturated calomel electrode are as contrast electrode).Data handling system: it is to be moved with computing machine by constant potential to constitute, and carries out the collection of data by the control of software, analyzes and handles.Utility appliance comprises that ccd video camera links to each other by video card with computing machine, and ccd video camera is transferred to the situation of working electrode to carry out in the computing machine putting after the software control and is presented on the display.
The present invention has following advantage:
1. kapillary is to be made by macromolecular material, the shortcoming of having avoided glass tube in the past very easily to damage.
2. glass tube need be controlled contacting of solution and sample with silica gel, and the easier control of macromolecule kapillary does not need silica gel.
3. working electrode, contrast electrode and auxiliary electrode all design on a device, have avoided the generation of bubble.
4. compact conformation of the present invention, reasonable in design, easy to make.

Embodiment
Be elaborated below in conjunction with the structure and the analytic process thereof of drawings and Examples to microscopic electrochemical analyzer provided by the invention.
As shown in Figure 1, microscopic electrochemical analyzer provided by the invention, by electrode integrating device 1, optical microscope 7, potentiostat 10, ccd video camera 8 and computing machine 9 link to each other by video card, and ccd video camera is transferred to the situation of working electrode and carries out in the computing machine being shown enlarged on the display after the software control.Electrode integrating device 1 links to each other with syringe 6 by connecting pipe 5, and syringe plays solution and provides and seal the work pool that makes electrode integrating device 1 formation microscopic electrochemical, and this device has compact conformation, convenience operation.
As shown in Figures 2 and 3, in the present invention, electrode integrating device 1 is by macromolecule kapillary 2, and platinum filament or spun gold 3 and Ag/AgCl electrode or saturated calomel electrode 4 constitute.Macromolecule diameter capillaceous has higher-strength at 0.1-1mm, and has plug-and-play feature, and operation is very easy.The auxiliary electrode of platinum filament or gold filigree conduct reaction in device 1.It is that microsize and device 1 also have plug-and-play feature that Ag/AgCl electrode or saturated calomel electrode are selected for use, and it is as the contrast electrode of reaction.
The concrete operations of microscopic electrochemical analyzer of the present invention are:
(a) the electrode integrating device is fixed on the optical microscope, then the macromolecule kapillary is linked to each other with the electrode integrating device respectively with connecting pipe.
(b) with most advanced and sophisticated exit capillaceous rubber temporarily sealing, loading required solution with syringe is injected in the electrode integrating device by connecting pipe, up to the whole space of solution chengman, and after bubble gone out clearly from the openend of contrast electrode, contrast electrode is inserted on the electrode integrating device.The electrochemical reactive tank of such sealing has just been finished.Then sealing rubber capillaceous is taken away, solution just can flow out from tip capillaceous by the control of syringe.
(c) sample to be determined is put into selected zone to be measured on the sample stage of optical microscope, kapillary is turned to the top in zone to be measured and contact, in the process of contact, monitor by the CCD gamma camera with sample, signal is amplified and pass on the screen of computing machine, avoid the leakage of solution.
(d) working electrode, contrast electrode links to each other with potentiostat with auxiliary electrode, and potentiostat and computing machine are controlled by related software.Control Software is collected experimental data, detects and analyzes.
The variation that can come the observation sample pattern with microscope after (e) test is finished.And change fresh solution with syringe.
