Abstract
The utility model relates to a carbon paste electrode on renewable surface, it uses insulating polymer material as the shell, fills simple carbon paste or the carbon paste who thoughtlessly has biological enzyme preparation, biological tissue piece, electrochemical catalyst and antigen antibody in electrically conductive inside lining to constitute electrochemical electrode and biosensor. The screw rod at the tail of the electrode is rotated to extrude the carbon paste from the electrode port, a new electrode surface is generated after the carbon paste is wiped, and the resistance value in the electrode is independent of the content of the carbon paste in the carbon paste storage chamber due to the conductive lining with fixed position in the electrode body. The tail part of the electrode is filled with carbon paste, and air exhaust and sealing measures are taken, so that the surface shape of the electrode is not influenced by the air pressure of the use environment and is kept stable.
Description
The utility model belongs to the carbon paste electrode on renewable surface.
When measure a kind of material in solution content or when studying the electrochemical process of a kind of material at electrode surface, use two kinds of electrodes usually, i.e. solid electrode and carbon paste electrode.Solid electrode comprises metal electrode, carbon and glass-carbon electrode, after using once, produces new electrode surface with lapping mode usually, and process of lapping is wasted time and energy.Talanta, 38(1), 107-110(1991); Analytical Chimica Acta, 273,219-227(1993); Analytist, 118, the 53-57(1993) carbon paste electrode that waits document to report, its common feature is, is shell with the insulated pipes used, and inside plug is with metal bar, leaves the hole at an end of pipe, and some metal bar of the other end exposes, as outer lead.In the hole, fill carbon paste, when upgrading the carbon paste surface, promote metal bar, extrude carbon paste, with clean paper unnecessary carbon paste is wiped again.The problem of following several aspects in use can appear in this class carbon paste electrode:
1, the electric transmission of electrode interior is to be undertaken by carbon paste in the housing and metal bar, when the carbon paste stereomutation in the housing, the path of electron motion also changes simultaneously, therefore the resistance value of electrode interior changes with the volume of carbon paste in the shell, thereby has influenced the consistance of performance in the electrode use.
2, fill carbon paste by hole one end usually, therefore, often leave bubble between carbon paste and the metal, be difficult to get rid of, not only cause contact resistance to increase, and when in low, hyperbaric environment, using, because of bubble volume changes, thereby influenced the shape of electrode surface, the performance of electrode also changes thereupon.
3, during the wiping electrode surface, use paper or flat glass usually, often stick together and carbon paste in the holder tail phenomenon of electrode surface, be difficult to form flat circle plate-like electrode surface, influence the reappearance of electrode.
The purpose of this utility model provides a kind of carbon paste electrode of renewable surface and is used to polish the trough of belt flat metal or the glass of electrode surface, overcomes the existing problem of carbon paste electrode with this.
The technical solution of the utility model accompanying drawings is as follows:
Accompanying drawing 1(a) being the synoptic diagram of the carbon paste electrode on renewable surface, (b) is the synoptic diagram of electrode protection cover.
Among the figure; 1 is housing; adopt the insulation macromolecular material to make; housing top is carbon paste storeroom 17; the middle part is fixing neck 16; have external thread; be used for fixing electrode protection cover 7, electrode protection cover 7 is tubular, and an end of tubular has internal thread to match with fixing neck 16; there is the electro-conductive liner made from the inert metal pipe 5 electrode stem 18 inboards; metal washer 4 is arranged at the bottom in carbon paste storeroom 17, and its center is porose, and an end of tubulose electro-conductive liner 5 directly inserts in the center pit of metal washer 4; tubulose electro-conductive liner 5 and metal washer 4 also can mold pressings; moulding by casting becomes one it, and lead 13 passes housing 1 and joins with the outside extruding of metal gasket 4.One hollow stem stem 3 is arranged in the carbon paste storeroom 17, is concave surface 12 towards an end of carbon paste 6, and the other end is female hole 11, middlely connect with hole 14, and be transition fit between the inwall of the outer wall of stem stem 3 and carbon paste storeroom 17, coating Seal Oil when adorning.Screw thread in the hole 11 has two effects, and the one, the encapsulant of fixedly inserting, the 2nd, in the hole, can screw in suitable lead screw, so that stem stem 3 is extracted from electrode chamber.In the port of carbon paste storeroom 17 lead screw 2 is arranged, the one side that contacts with stem stem 3 is the plane, there is stria 10 at the center of another side, this stria 10 is to be used for precession or to screw out lead screw 2, when precession lead screw 2, can promote stem stem 3, and can extrude carbon paste 6, clean and produce new electrode surface after the carbon paste from the port one 5 of electrode stem 18.Because the liner 5 of conduction and the stationkeeping of packing ring 4, and lead 13 joins with packing ring 4, thereby the content of carbon paste has nothing to do in the resistance value that has guaranteed electrode interior and the carbon paste storeroom.Because carbon paste is to insert cavity from the electrode afterbody, and get rid of inner airs, fill threaded hole 11, thereby make the electrode surface shape not be subjected to the barometric pressure effect of environment for use and keep stable with encapsulant with the concave surface 12 and the center pit pipe 14 of stem stem 3.
Accompanying drawing 2 is the polishing dull and stereotyped synoptic diagram of trough of belt.
Dull and stereotyped 9 can adopt glass or metal material to make, and stria 8 are arranged on dull and stereotyped 9, when electrode head on flat board during paddling, unnecessary carbon paste is left in the stria 8, planar section flattens electrode surface.
The utility model is compared with common carbon paste electrode, and following advantage is arranged:
1, the electro-conductive liner of stationkeeping has guaranteed that the carbon paste electrode internal resistance does not in use change with the variation of carbon paste volume in the housing, thereby has guaranteed the consistance of its performance.
When 2, upgrading electrode surface, the extrusion capacity of carbon paste can be by the lead screw of the rotation electrode afterbody microcontroller of running business into particular one, thereby has increased the recycling rate of waterused of electrode, and this lead screw is hidden in the housing, in use is difficult for touching, and is maintained fixed the position.
3, owing to the afterbody from electrode is filled carbon paste, and take to get rid of the structural design and the seal approach of inner air, when having guaranteed that this electrode uses in the high and low pressure environment, the carbon paste volume does not change in the housing, thereby the proterties that has guaranteed electrode surface does not change yet.
4, electrode head has protective sleeve, is convenient to store and transportation.
5, adopted the dull and stereotyped polishing of trough of belt electrode surface, guaranteed that polishing electrode is quick, easy, clean.
The utility model is applicable to the Basic Experiment Study of galvanochemistry and Electroanalytical Chemistry; also can be used for making the enzyme electrode biology sensor of measuring multiple material; can be used as the electrochemical detector of Anodic Stripping Voltammetry Determination heavy metal ion; be specially adapted in the miniature low-lift pump system a kind of concentration of material in the on-site measurement skin suction filtration liquid; be the utility of clinical monitoring, Physiology and biochemistry, pharmacology and metabolic processes research, also be applicable to fields such as clinical examination, health care, labour protection, environmental monitoring, food industry, sweat control, Chemical Manufacture.
