Abstract
A kind of compound pH electrodes of open reference liquid border, it includes shell (1), case nose is equipped with sensitive ball bubble (2), sensitive ball bubble (2) is built with interior reference solution (3), interior reference filamentary silver (4) one end is in the internal cavity (101) of shell (1), the other end is stretched into sensitive ball bubble (2), outer reference filamentary silver (5) is isolated in the external cavity (102) of outer (1) shell with interior reference filamentary silver (4), it is characterised in that：In the external cavity (102) in shell (1), it is reference liquid border to offer hole (103) on the shell (1) to outer reference gel (6).The compound pH electrodes of the open reference liquid border can for a long time work in the sample polluted containing a large amount of fine suspensions, and reference liquid border is not plugged up and influences electrode life.
Description
Technical field
The utility model belongs to species analysis Instrument technology field, is exactly specifically to be related to a kind of open reference liquid border
Compound pH electrodes, reduce the cleaning difficulty of electrode.
Background technology
Combination electrode has been widely used for the measurement of pH value, the electricity that pH glass electrodes and reference electrode are combined
Pole is exactly pH combination electrodes.At present in test process according to the characteristics of test sample, using different reference structures and sensitivity
Glass ball bulb, is further divided into the electrode special suitable for different application environment by pH combination electrodes.
PH electrode test technologies are highly developed, but in actual applications, have many testing samples to contain a large amount of
Suspension is sticky in itself, is easily adhered the measurement end in pH electrodes, the performance of pH electrodes is declined rapidly.It is particularly easy
Electrode Reference system liquid border is set to be blocked, it is difficult to recover by general cleaning method.
The liquid border of common pH electrodes is usually loose structure or narrow slit structure, is difficult to once contaminated thing stains and blocks
By thoroughly cleaning, so as to the life-span for causing pH electrodes greatly shortens.
It is susceptible to block difficult cleaning of defect to improve existing PH combination electrodes liquid border, occurring in that on the market can
Disengaged glass or glass plastic ground liquid border, the sample strong for measuring contaminative.Once electrode is contaminated hydraulic performance decline,
Ground can be disengaged to be cleaned.But the disengaging of small range can only be done due to existing ground, once pollutant enters ground
Inner side is even attached on the inwall of electrode shell or interior electrode, it may be difficult to which thoroughly cleaning, long term accumulation will influence electrode performance,
Measurement is reduced, if electrode shell thoroughly dismantled, outer reference system is then easily damaged or dries up and is difficult to restorability, together
Sample can shorten electrode life.
Utility model content
The technological deficiency that the purpose of this utility model is difficult to clean aiming at existing PH combination electrodes, there is provided
A kind of compound pH electrodes of open reference liquid border, the compound pH electrodes of the open reference liquid border can be containing a large amount of tiny
Worked for a long time in the sample of suspended solid pollutant, reference liquid border is not plugged up and influences electrode life.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of open reference liquid border of the utility model design is combined pH electrodes,
It includes shell, and case nose is equipped with sensitive ball bubble, and the sensitive ball bubble is built with interior reference solution, interior reference filamentary silver one end dress
In the internal cavity of shell, the other end is stretched into sensitive ball bubble, and outer reference filamentary silver is silver-colored with interior reference in the external cavity of shell
Silk isolation, it is characterised in that：In the cased external cavity of outer reference gel, hole is offered on the shell for reference liquid connects
Boundary.
Further, the internal cavity is connected with sensitive ball bubble.
Beneficial effect
The compound pH electrodes of a kind of open reference liquid border that the present invention is provided, the compound pH electricity of the open reference liquid border
Pole can for a long time work in the sample polluted containing a large amount of fine suspensions, and reference liquid border is not plugged up and influences electrode
Life-span.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further.
Embodiment
As shown in Figure 1, the compound pH electrodes of a kind of open reference liquid border, it includes shell 1, and case nose is equipped with quick
Sense ball bubble 2, built with interior reference solution 3, interior one end of reference filamentary silver 4 is mounted in the internal cavity 101 of shell 1 the sensitive ball bubble 2,
The other end is stretched into sensitive ball bubble 2, and outer reference filamentary silver 5 is isolated in the external cavity 102 of shell 1 with interior reference filamentary silver 4, and it is special
Levy and be：Outer reference gel 6 offers hole 103 for reference liquid connects in the external cavity 102 in shell 1 on the shell 1
Boundary.
The internal cavity 101 is connected with sensitive ball bubble 2.
The surface attachment silver chloride layer of outer reference filamentary silver 5 is produced by special process, with longer than conventional electroplating method
Service life.Open liquid border is that the aperture of a diameter of 1mm directly makes outer reference gel 7 be contacted with sample.Outer reference
Gel 7 be solid electrolyte, with sample Long Term Contact after can still keep script state.
The compound pH electrodes of a kind of open reference liquid border that the present invention is provided, the compound pH electricity of the open reference liquid border
Pole can for a long time work in the sample polluted containing a large amount of fine suspensions, and reference liquid border is not plugged up and influences electrode
Life-span.
