Abstract
The utility model provides an electrochemical onsite quartz crystal micro balance detection pool, which is characterized in that a fixed sealing part of a quartz-crystal working electrode is integrated on a back sealing cover with a D-shaped insertion opening, and is fixed by two H-shaped screws of coarse pitch integrally; the inner part of a main body of a cylindrical liquid cavity is provided with a standard quartz-wafer interface slot; an auxiliary electrode is surrounded on the wall of the upper part of the main body of the liquid cavity, and the auxiliary electrode is provided with a reference-electrode inclined hole. Due to the design, the utility model has the advantages that the risk of damage of long-term-use screw threads is avoided; the service life of the whole pool body is prolonged; the steps and complexity of installation are reduced; the factors of leakage are reduced at the same time, and thus, electrochemical detection is convenient.
Description
The utility model belongs to the design of the on-the-spot QCM (Quartz Crystal Microbalance) detection cell of galvanochemistry.
The EG﹠amp of the U.S.; G (Princeton Applied Research) company is the supporting cover detection cell that provides in on-the-spot QCM (Quartz Crystal Microbalance) (the Electrochemically Quartz Crystal Analyzer) instrument of its galvanochemistry.The standard interface that the quartz wafer that this detection cell provides can be provided with it is complementary, this can make contain metal film the quartz wafer working electrode better sealing-in in detection cell, thereby prevented the leakage of electrolytic solution on working electrode effectively.This cover detection cell uses teflon (Teflon) as material of main part, and uses ten screws with sealing-in liquid pool cavity, fixing contact conductor and the pond body bonnet on quartz wafer, the wafer thereon.Because teflon is softer, so the screw on it very easily deforms when the precession screw, causes poorly sealed, the serious whole detection cell that then causes to use.Such method for designing not only complicated operation, be difficult to use, and this detection cell life-span is shorter, brings great waste (the about $200 of the detection cell of an import).
The objective of the invention is to design a kind of by cylindric sap cavity main body and have the bonnet of D shape socket and have that the circular upper cover of baffle ring forms, inside is provided with the on-the-spot QCM (Quartz Crystal Microbalance) detection cell of galvanochemistry of standard quartz wafer interface slot.
The utility model is partially integrated in a few of fixing seal electrode wafer on the bonnet, makes installation steps reduce by two steps, and has reduced by six fixed screws.The main part of liquid pool cavity and fixed electorde is integrated, reduce by two step installation steps and two fixed screws again, and further reduced the factor of leaking.Because the screw that is used to seal reduces, therefore can there be bigger space to be used for fixing sealing, so use the I-shaped screw that has than coarse pitch to fix.Wafer is become concentric with outer chamber with the Interface design of sap cavity, be easy to like this process and interface is polished, thereby can obtain extremely excellent sealing effectiveness.In addition, platinum auxiliary electrode and movable contrast electrode hole are directly designed at Chi Tizhong, made things convenient for Electrochemical Detection.
Embodiment of the present utility model is described below in conjunction with the accompanying drawings: accompanying drawing 1 is the on-the-spot QCM (Quartz Crystal Microbalance) detection cell of a galvanochemistry synoptic diagram, the I-shaped screw (1) of a pair of symmetrical distribution cooperates with pad (2) and is used for fixing bonnet (3), bonnet (3) has D shape socket, the silicone rubber seal packing ring (4) that is used for fixing the annular of a pair of corresponding working electrode quartz wafer (5) installation, sap cavity main body (6) is one cylindric, top has one section bore to be slightly larger than inner major diameter, and be complementary with the circular upper cover that has baffle ring (9), one square recess is arranged at the bottom, one standard quartz wafer interface slot is arranged at recess top, one baffle ring is arranged at interface slot top, be used for being connected with packing washer (4), quartz wafer (5) is embedded in the standard quartz wafer interface slot of sap cavity main body (6) bottom, have on the wall of sap cavity main body (6) near the through working electrode quartz wafer (5) of an inclined hole (7), on the chain-wales of sap cavity main body (6) internal upper part greater than the inner major diameter place, around fixing platinum filament auxiliary electrode (8) thereon, electrode one end is by drawing on sap cavity main body (6) wall.
Therefore the detection cell of the utility model design is easy to fabrication and processing, simple installation because five parts and two screws are only arranged, and particularly has the quartz wafer that can use import easily, and the integrated level height is leak-proof good, and long service life.
