First, leakage oxygen analyzer must be strictly leak detection before the initial opening. Oxygen analyzers can only obtain accurate data results without rigorous leakage. Any imperfections at any connection points, solder joints, valves, etc., will cause oxygen in the air to infiltrate into the pipeline and the oxygen analyzer, resulting in a high oxygen content.
II. Contamination When reusing the oxygen analyzer, it is first necessary to pay attention to whether or not air is leaked when connecting the sampling line of the oxygen analyzer, and the air leaked into the oxygen analyzer must be blown cleanly to avoid making a lot of oxygen pass through as much as possible. Oxygen Analyzer Sensors to Extend Sensor Life. In the purification process of the pipeline system, in order to shorten the purification time, a certain method is needed. Generally, high-pressure gas discharge and small-flow rate blowing are used to alternately purge the oxygen analyzer pipeline.
Third, the choice of pipe material oxygen analyzer pipeline material and surface roughness will also affect the sample gas oxygen content changes. In general, plastic pipes, rubber pipes, etc. should not be used as connecting pipes. Oxygen analyzers usually use copper or stainless steel tubes. For ultra-micro analysis (<0.1ppm), polished stainless steel tubes must be used.
Fourth, the simplification of the airway system and the microanalysis of the clean oxygen analyzer must effectively eliminate the pollution caused by dead angles in the various pipes, valves, and meters on the airways. Therefore, the oxygen analyzer gas system should be simplified as much as possible, and connectors with small dead angles should be used. Also, avoid the use of water seals, oil seals, and wax seals to prevent the dissolved oxygen from escaping to cause pollution, and to avoid the addition of purifying equipment that can easily cause contamination when the sample gas is led to the inlet of the oxygen analyzer. Only in this way can the system be clean and the data obtained be accurate.
