Technical field
The invention belongs to technical field of electrochemistry, relate to a kind of electrochemical investigating pond.
Background technology
Galvanochemistry is as one of branch of chemistry, is the science that the charged and electron transfer that taken place on the interface that forms of two types of conductors of research (electronic conductor is like metal or semiconductor, and ion conductor, like electrolyte solution) changes.Galvanochemistry is applied in the check and analysis of biomolecule by domestic and international scientist.Indium tin oxide-coated glass (ITO) and gold plaque electrode are the pellet electrodes that is in daily use; Generally; The scientific research personnel just is placed into pellet electrode in the electrochemical investigating pond of glass or quartzy material; In this case, the actual detected area of electrode is not easy control, directly electrochemical detection of influence and interpretation of result.Common conductive clip neither be very stable with contacting of pellet electrode, and electrode comes off in the Electrochemical Detection process easily.That the electrochemical investigating pond of used glass or quartzy material has is frangible, use shortcoming such as inconvenience.
Summary of the invention
To existing electrochemical investigating pond great majority is glass material; Exist frangible, use shortcomings such as inconvenience, detectable large usage quantity; And not being suitable for the detection of pellet electrode, the present invention provides a kind of and is convenient to fixedly pellet electrode, and the electrochemical investigating pond of its actual area of detection.
Electrochemical investigating pond of the present invention comprises two parts at the bottom of pond body and the pond; Wherein the pond body is the cavity that is made up of cylindrical pond and disc base concentric; The top of cylindrical pond sidewall is provided with pore, and disc base is provided with the copper post, and disc base is connected with at the bottom of the pond through screw.
Detection cell simplicity of design of the present invention is exquisite; Utilize the elastic metallic post to realize and the pellet electrode excellent contact, practical, solid non-friable; The detectable consumption is few; The electrode used therein area is little, and the actual detected area of fixed test electrode accurately, calculates for accurate quantitative analysis and haves laid a good foundation.In scientific research and the commercial production of this design aspect Electrochemical Detection good prospects for application is arranged all.

Embodiment one: shown in Fig. 1 ~ 6, the detection cell of this embodiment comprises pond body 1 and bottom 2 two parts.Said pond body 1 cavity for constituting by cylindrical pond 3 and disc base 4 concentrics, the top of cylindrical pond 3 sidewalls is provided with pore 5, disc base 4 is provided with copper post 6, disc base through screw with 2 be connected at the bottom of the pond.
In this embodiment, said detection cell material can be macromolecular materials such as polymethyl-benzene olefin(e) acid methyl esters (PMMA), teflon.
In this embodiment, the internal diameter in said cylindrical pond 3 is 1～1.5 centimetre, and external diameter is 1.4～1.9 centimetres, and height is 2～4 centimetres.
In this embodiment, said disc base 4 thick 0.3～0.8 centimetre, external diameter is 4～5 centimetres.
In this embodiment, 2 measure-alike with disc base 4 at the bottom of the said pond, but bottom area can be greater than the area of disc base, and thickness 3～8 mm are good.
In this embodiment, the center of said disc base 4 is vertically arranged with through hole, and through hole is made up of last hole 4-1 and following hole 4-2; The internal diameter of last hole 4-1 is less than the internal diameter of following hole 4-2; The degree of depth of following hole 4-2 is 1.3～1.4 millimeters, and is consistent with the external diameter of elastic caoutchouc circle 7, just puts down elastic caoutchouc circle 7; And the thickness of elastic caoutchouc circle 7 state of nature is 1.5 millimeters; Purpose is to make the just outstanding sub-fraction of rubber ring, is contacting some deformation of back with electrode, thereby is reaching the purpose that prevents that detection cell kind sample from leaking.
Embodiment two: what this embodiment and embodiment one were different is, said cylindrical pond 3 internal diameters are 1 centimetre, and external diameter is 1.4 centimetres, and height is 2.5 centimetres.Disc base 4 thick 0.5 centimetre, diameter is 4 centimetres.Disc base 4 peripheries are evenly distributed four screw holes 7 and are used for the bottom 2 of pond body 1 and detection cell is combined, and bottom 2 is that 4 centimetres, thickness are 5 millimeters disk for external diameter.Electrode for use is sandwiched between the pond body 1 and bottom 2 of detection cell.0.3 centimeters in distance circle cylindricality pond 3 has a rubber-like copper post 6 (0.1 centimetre of diameter) on disc base 4, and this copper post 6 is used for combining with pellet electrode.It is 0.1 centimetre pore 5 that distance circle cylindricality liquid storage tank 3 tops 0.3 centimeters has an internal diameter, and this pore 5 is used for platinum filament is inserted into detection cell to electrode.For preventing that solution from leaking, and can place an elastic caoutchouc circle 9 between pond body 1 and pellet electrode.0.8 centimetre of the external diameter of elastic caoutchouc circle 9,0.5 centimetre of internal diameter.
