, online air monitoring and research means, particulate pollutant and sour gas are directly inhaled using unique sampler
It receives in water phase, reuses ion chromatography and monitor its ingredient, whole process is performed fully automatic.Its collected liquefied sample can be with
Other analyzers are directly combined.
When detecting Atmospheric Liquid Phase, generally requires while measuring compared with entry (such as pH value, ORP, conductivity, and detection
The reaction that sample occurs under ultraviolet irradiation condition), but since the sample that can be collected is less, each single item content is carried out respectively
When measurement, the loss of sample is caused, and is unable to reach the reaction that sample is occurred and carries out real-time monitoring.
Summary of the invention
The object of the present invention is to provide a kind of water-soluble online flow cell of atmosphere multi-parameter, in order to improve the efficiency of detection
The utilization rate of sample no longer detects one by one by a variety of test electrode sets on a flow cell；And the flow cell and online

To achieve the above object, present invention provide the technical scheme that
A kind of online flow cell of water solubility atmosphere multi-parameter, including flow cell ontology, are equipped with electrode sockets on flow cell
And inlet, the electrode sockets are electrode thread socket, including first electrode socket and second electrode socket, are respectively used to insert
Enter pH electrode and ORP electrode；Conductivity electrode, the conductivity electrode of insertion are inserted into using thread socket in flow cell cavity one end
It is connected with on-line checking Conjoint Analysis system, the real-time detection to Atmospheric Liquid Phase constituent analysis can be reached；On flow cell
There is a tiny inlet opening in portion center, the aerosol for receiving to flow out from MARGA system, and the flow cell cavity other side is outflow
Hole；The flow cell is detected simultaneously for multiple electrodes.
Further, tap hole is externally connected to a timing valve, can carry out timesharing piecewise analysis inspection to the liquid of collection
It surveys.
Further, when valve is closed, collected liquid is saturated with cavity, and electrode is enable to come into full contact with liquid,
Reach testing goal.
Further, when the conductivity electrode of the thread socket of described flow cell cavity one end is taken out, the thread socket
It can be used as second outflow hole.
Compared with prior art, the beneficial effects of the present invention are:
