Abstract
The invention relates to an open type reference solution abutment composite pH electrode, which comprises a shell (1), wherein a sensitive bulb (2) is arranged on the front end of the shell; an internal reference solution (3) is loaded in the sensitive bulb (2); one end of an internal reference sliver silk (4) is loaded in an inner cavity (101) of the shell (1), and the other end of the internal reference sliver silk (4) stretches into the sensitive bulb (2); an external reference sliver silk (5) is loaded in an outer cavity (102) of the shell (1) and is isolated from the internal reference sliver silk (4). The open type reference solution abutment composite pH electrode is characterized in that an external referencegel (6) is loaded in the outer cavity (102) of the shell (1), and a hole (103) is formed on the shell (1) and is used as a reference solution abutment. The open type reference solution abutment composite pH electrode can work in a sample containing a large number of small suspended solid pollutant for a long time, the reference solution abutment cannot be blocked, and the service life of the electrode cannot be influenced.
Description
Technical field
The invention belongs to species analysis Instrument technology field, it is exactly specifically to be related to a kind of open reference liquid junction to be combined
Ph electrode, reduces the cleaning difficulty of electrode.
Background technology
Combination electrode has been widely used for the measurement of ph value, the electricity that ph glass electrode and reference electrode are combined
Pole is exactly ph combination electrode.The feature according to test sample in test process at present, using different reference structures and sensitivity
Ph combination electrode is divided into the electrode special being applied to different application environment by glass ball bulb further.
Ph electrode test technology is highly developed, but in actual applications, has a lot of testing samples may contain a large amount of
Float or itself is sticky, is easily adhered the measurement end in ph electrode, so that the performance of ph electrode is declined rapidly.Particularly easy
Electrode Reference system liquid junction is made to be blocked it is difficult to recover by general cleaning method.
The liquid junction of common ph electrode is usually loose structure or narrow slit structure, stains blocking once contaminated thing and is just difficult to
By thoroughly cleaning, thus leading to the life-span of ph electrode to greatly shorten.
It is susceptible to block difficult cleaning of defect to improve existing ph combination electrode liquid junction, occurring in that on the market can
Disengaged glass or glass plastic ground liquid junction, the sample strong for measuring contaminative.Once electrode is contaminated hydraulic performance decline,
Ground can be disengaged be carried out.But because existing ground can only do the disengaging of small range, once pollutant enter ground
Inner side is even attached on the inwall of electrode shell or electrode it may be difficult to thoroughly cleaning, and long term accumulation will affect electrode performance,
Reduce measurement, if electrode shell is thoroughly dismantled, outer reference system is then easily damaged or dry to be difficult to restorability, with
Sample can shorten electrode life.
Content of the invention
The purpose of the present invention is aiming at the technological deficiency that existing ph combination electrode is difficult to clean, and provides one kind
Open reference liquid junction is combined ph electrode, and this open reference liquid junction is combined ph electrode and can contain tiny suspension in a large number
Work for a long time in the sample of thing pollution, reference liquid junction is not plugged up and affects electrode life.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of open reference liquid junction of present invention design is combined ph electrode, and it wraps
Include shell, case nose steeps equipped with sensitive ball, described sensitivity ball steeps built with interior reference solution, and interior reference filamentary silver one end is contained in outer
In the internal cavity of shell, the other end stretches in sensitive ball bubble, outer reference filamentary silver be contained in the external cavity of shell with interior reference filamentary silver every
From it is characterised in that: in the cased external cavity of outer reference gel, described shell offers hole be reference liquid junction.
Further, described internal cavity is connected with sensitive ball bubble.
Beneficial effect
A kind of open reference liquid junction that the present invention provides is combined ph electrode, and this open reference liquid junction is combined ph electricity
Pole can work in the sample polluting containing a large amount of fine suspension for a long time, and reference liquid junction is not plugged up and affects electrode
Life-span.
Brief description
Accompanying drawing 1 is the structural representation of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be further described.
Embodiment
As shown in Figure 1, a kind of open reference liquid junction is combined ph electrode, and it includes shell 1, and case nose is equipped with quick
Sense ball bubble 2, built with interior reference solution 3, interior reference filamentary silver 4 one end is contained in the internal cavity 101 of shell 1 described sensitivity ball bubble 2,
The other end stretches in sensitive ball bubble 2, and outer reference filamentary silver 5 is contained in the external cavity 102 of outer 1 shell is isolated with interior reference filamentary silver 4, and it is special
Levy and be: outer reference gel 6 is contained in the external cavity 102 in shell 1, described shell 1 offers hole 103 and connects for reference liquid
Boundary.
Described internal cavity 101 is connected with sensitive ball bubble 2.
Outer reference filamentary silver 5 surface attachment silver chloride layer is produced by special process, has longer than conventional electroplating method
Service life.Open liquid junction is that the aperture of a diameter of 1mm directly makes outer reference gel 7 contact with sample.Outer reference
Gel 7 still can keep script state for after solid electrolyte, with sample Long Term Contact.
A kind of open reference liquid junction that the present invention provides is combined ph electrode, and this open reference liquid junction is combined ph electricity
Pole can work in the sample polluting containing a large amount of fine suspension for a long time, and reference liquid junction is not plugged up and affects electrode
Life-span.
