Determination of trace oxygen in gases - Electrochemical method
1 Scope
This standard specifies the use of electrochemical method for the determination of trace oxygen in the gas, including fuel cell method, Hertz battery method, zirconia concentration
Battery, ion flow, the original battery method, the instrument, calibration, test procedures, the results of processing and test reports made a request.
This standard applies to gases that do not react chemically with the chemical cell and do not interfere with the measurement. Measurement range. 0.01 × 10-6 (volume points
Number) to 1000 × 10-6 (volume fraction).
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
General rules for sampling safety of industrial chemical products GB/T 3723
GB/T 5274 Preparation of gas mixtures for gas analysis calibration

3 principle
3.1 Overview
The use of chemical batteries as a measure of oxygen in the gas sensor.
The gas to be measured in the appropriate form into the chemical battery, according to the oxygen in the chemical oxygen in the chemical characteristics of the battery, by measuring and oxygen
Content of a chemical function to determine the relationship between the potential of the chemical battery, or current, or conductivity and other physical quantities, to achieve the gas in the measured gas analysis
Determination.
3.2 fuel cell method
The battery used in the fuel cell method is a closed chemical charge consisting of an inert metal electrode (cathode), a lead electrode (anode) and an electrolyte
Pool. Oxygen in the gas diffuses into the cell through the polymer film, is reduced in the cathodic oxygen, and is oxidized at the anode lead. The battery reacts to electricity
The output signal of the flow sensor is proportional to the oxygen content in the gas.
The electrolyte of this type of equipment is acidic and alkaline two kinds of alkaline electrolyte is not suitable for the determination of trace oxygen in acidic gases, acidic
The solution is not suitable for the determination of trace oxygen in alkaline gases.
3.3 Hz battery method
The Hertz battery method uses a chemical cell consisting of a carbon alloy (cathode), a platinum wire (anode), and an electrolyte. Apply to the battery
Plus a DC voltage to provide electron transfer energy. The current generated by the battery reaction is the size of the sensor output signal and the oxygen content in the gas
Proportional.
This type of instrument is suitable for the determination of trace oxygen in inert and inactive gases, including hydrogen, nitrogen, carbon monoxide, freon, carbon
Compounds and so on.
