specific Embodiment approach 1

[0015] Specific implementation mode one: as Figure 1~6 As shown, the detection cell in this embodiment includes two parts: a cell body 1 and a bottom 2 . The pool body 1 is a cavity composed of a cylindrical pool 3 and a disc base 4 concentrically. The upper part of the side wall of the cylindrical pool 3 is provided with a fine hole 5, and the disc base 4 is provided with a copper column 6. The disc base is connected with the pool bottom 2 by screws.

[0016] In this embodiment, the material of the detection cell may be a polymer material such as polymethyl methacrylate (PMMA), polytetrafluoroethylene or the like.

[0017] In this embodiment, the inner diameter of the cylindrical pool 3 is 1-1.5 cm, the outer diameter is 1.4-1.9 cm, and the height is 2-4 cm.

[0018] In this embodiment, the disc base 4 has a thickness of 0.3-0.8 cm and an outer diameter of 4-5 cm.

[0019] In this embodiment, the size of the pool bottom 2 is the same as that of the disc base 4 , but the a...

specific Embodiment approach 2

[0021] Embodiment 2: This embodiment differs from Embodiment 1 in that the inner diameter of the cylindrical pool 3 is 1 cm, the outer diameter is 1.4 cm, and the height is 2.5 cm. The disc base 4 is 0.5 cm thick and has a diameter of 4 cm. Four screw holes 7 are evenly distributed around the disc base 4 for combining the cell body 1 with the bottom 2 of the detection cell. The bottom 2 is a disc with an outer diameter of 4 cm and a thickness of 5 mm. The electrodes to be used are sandwiched between the cell body 1 and the bottom 2 of the detection cell. There is an elastic copper column 6 (diameter 0.1 cm) on the disc base 4 at a distance of 0.3 cm from the cylindrical pool 3, and the copper column 6 is used to combine with the sheet electrode. There is a fine hole 5 with an inner diameter of 0.1 cm at a distance of 0.3 cm from the top of the cylindrical liquid reservoir 3, and the fine hole 5 is used for inserting the platinum wire counter electrode into the detection cell....

Abstract

An electrochemistry detection cell belongs to the technical field of electrochemistry, and aims to overcome defects of most conventional electrochemistry detection cells made of glass, such as easiness in breaking, convenience in use, incongruity in detection of piece-shaped electrodes and the like. The electrochemistry detection cell comprises two parts including a cell body (1) and a cell bottom (2), wherein the cell body (1) is a cavity formed by a cylindrical cell (3) and a round disk-shaped base (4) which are coaxial; a slim hole (5) is formed at the upper part of the lateral wall of the cylindrical cell (3); a copper column (6) is arranged on the round disk-shaped base (4); and the round disk-shaped base is connected with the cell bottom (2) via a screw. The electrochemistry detection cell is simple and smart in design, and is well contacted with the piece-shaped electrodes by utilizing an elastic copper column (6), has high practicability, is less in consumption of reagent for test, firm and low in breaking probability, and can fix the electrodes and detect the practical detection area thereof, so as to establish a good foundation of accurate quantitative analysis and calculation.

Description

technical field [0001] The invention belongs to the technical field of electrochemistry and relates to an electrochemical detection cell. Background technique [0002] As one of the branches of chemistry, electrochemistry is a science that studies the charge and electron transfer changes at the interface formed by two types of conductors (electronic conductors, such as metals or semiconductors, and ion conductors, such as electrolyte solutions). Electrochemistry has been applied to the detection and analysis of biomolecules by scientists at home and abroad. Indium tin oxide conductive glass (ITO) and gold flake electrodes are very commonly used sheet electrodes. Usually, researchers just place the flake electrodes in an electrochemical detection cell made of glass or quartz. In this case, the electrode The actual detection area is not easy to control, which will directly affect the electrochemical detection and result analysis. The contact between the ordinary conductive c...
