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 GB/T 5275.11 Gas analysis - Dynamic volume method for the preparation of calibrated gas mixtures - Part 11.

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. ......
