The transmission windows on the cavity body is movable, namely the outer edge of the window is provided with screws and the cavity body of the flowing pond is provided with inner screw thread which is matched with the screw thread at the outer edge of the window. The utility model provides a multi-functional spectral miniature electrochemical flowing pond which is used for routine electrochemical study and is not only used for fixing pond volume and optical length but also suitable for a multi-functional spectral miniature electrochemical flowing pond in flowing and injecting analysis and study and electrochemical study of site UV and visible spectrum.
Description
The utility model relates to a kind of spectroelectrochemistry analytical equipment, relates in particular to the miniature galvanochemistry flow cell of a kind of multi-functional spectroscopy.
Spectroscopy and galvanochemistry combine and the spectroelectrochemistry that forms, be different from traditional electrochemical method, can on instantaneous and molecular level, obtain galvanochemistry information, follow the trail of the variation of intermediate, reactant and the product of electrochemical reaction, obtain thermodynamics and kinetic parameter, for definite reaction mechanism provides direct evidence,, requisite method in the bioelectrochemistry research.
Spectrum electrochemical pool is the core component of spectroelectrochemistry.Reasonably design, structure adjustable, the improvement of performance and the expansion of purposes remain focus that people pay close attention to and the difficult point of still needing and capturing.Yet existing spectrum electrochemical pool difficulty reaches above-mentioned functions, and for example, pond volume and light path are fixed, and is difficult to be suitable for Flow Injection Analysis research and on-the-spot ultraviolet, visible spectrum electrochemical research.
The purpose of this utility model is: a kind of conventional electrochemical research that is applicable to is provided, can be used for pond volume and light path fixes, be applicable to that again pond volume and light path are adjustable, make study sample not be subjected to the restriction of volume and concentration, be applicable to the miniature galvanochemistry flow cell of multi-functional spectroscopy of Flow Injection Analysis research and on-the-spot ultraviolet, visible spectrum electrochemical research.
The purpose of this utility model is achieved in that the miniature galvanochemistry flow cell of a kind of multi-functional spectroscopy, comprise on a flow cell cavity, the cavity a pair of transmission window is set, working electrode is set in the cavity, to electrode and reference electrode, it is characterized in that transmission window is movable on the described cavity, promptly the outer rim at window is provided with screw thread, on the flow cell cavity with the internal thread that also is provided with window outer rim screw thread coupling.
Along with transmission window screw thread moving on flight pitch on the flow cell cavity, the flow cell cavity volume is changing, and the pond volume is adjustable at three orders of magnitude, from 1 microlitre to 1 milliliter.I reaches 1 microlitre.Therefore, the pond light path is adjustable between 0.020 millimeter to 10 millimeters.I reaches 20 microns.The instrument of adapted such as BrukerRFS-66V Fourier transform infrared spectrometer and RFS-100 surface-enhanced Raman spectroscopy (SERS), the research of site infrare spectroelectrochemistry, Surface enhanced raman spectroscopy electrochemical research also are applicable to on-the-spot uv-vis spectra electrochemical research.
Characteristics of the present utility model are: can give full play to the synergy of galvanochemistry and multiple spectroscopy, obtain valuable information more.Be applicable to conventional electrochemical research, cyclic voltammetric, timing electric current (amount) etc.Also be applicable to Flow Injection Analysis research, only need a duplicate samples, just can obtain multiple information.Be applicable to field monitoring galvanochemistry synthetic product, rational in infrastructure, succinct, be easy to assembling, dismounting and cleaning.Especially can change multiple working electrode easily, overcome the comparatively single problem of spectrum electrochemical pool purposes before.Because the pond volume and the light path of the utility model design are adjustable, make study sample not be subjected to the restriction of volume and concentration.Thereby that is when sample concentration is too high, needn't dilute and only need shorten light path and cross when sample concentration and only need increase light path when low and make the research of biological sample not be subjected to the restriction of sample volume and concentration.Dirigibility improves greatly, has adapted to reagent costliness in the bioelectrochemistry research, the special requirement that sample size is few.Utilize this pond successfully to carry out coenzyme NAD, the research of biomolecule such as haemoglobin.The miniature electrochemical cell of multi-functional spectroscopy of the utility model design can be used as detecting device in flow analysis, based on this, with the flow injection technology, multi wavelength analysis method and electrochemical analysis Amperometric Detection Coupled combine, and have set up multi-wavelength flow-type spectroscopy electrochemical analysis system.Be providing more choices property of test analyte.
