When oxygen content analysis, especially trace oxygen analysis, is performed, the oxygen content in the air is as high as 21% O2. Therefore, if the improper handling, it can easily cause pollution and interference to the sample, and the analysis result data is incorrect. The main reason is the improper operation of the oxygen micro-oxygen analyzer. The following points affect the factors determined by the oxygen micro-oxygen analyzer.

1. leakage. The Oxygen Oxygen Analyzer must be strictly leak tested before it is first started. Oxygen micro-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 oxygen analyzer, resulting in a high oxygen content.

2. Pollution. When reusing the oxygen micro-oxygen analyzer, first of all, it is necessary to pay attention to whether air is leaked when connecting the sampling line of the oxygen analyzer, and it is necessary to blow the air leaked into the oxygen micro-oxygen analyzer seriously, and try not to make a lot of oxygen. Pass the oxygen micro-oxygen analyzer's 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 deflation and small-flow rate blowing are used to rapidly purify the oxygen micro-oxygen analyzer pipeline.

3. The choice of pipe material. Oxygen micro-oxygen analyzer pipeline material and surface roughness will also affect the change of oxygen content in the sample gas. In general, plastic pipes, rubber pipes, etc. should not be used as connecting pipes. Oxygen micro-oxygen analyzers usually use copper or stainless steel tubes. For ultra-micro analysis (<0.1ppm), polished stainless steel tubes must be used.

4. Gas system simplification and cleanliness. The microanalysis of Oxygen Micro-Oxygen Analyzer must effectively eliminate the contamination of the sample gas caused by dead angles in various fittings, valves, and meters on the gas line. Therefore, the oxygen micro 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, wax seals, etc. to prevent dissolved oxygen from escaping and causing pollution. It is also necessary to avoid the addition of purifying equipment that can easily cause contamination when the sample gas is led to the inlet of the oxygen micro-oxygen analyzer. Only in this way can the system be clean and the data obtained be accurate.
