Summary Oxygen analysis instruments can be divided into three types according to different principles: fuel cell oxygen analyzer, zirconia sensor and magnetic oxygen analyzer.
Oxygen analysis instruments can be divided into three types according to different principles: fuel cell oxygen analyzer, zirconia sensor and magnetic oxygen analyzer.There are many matters needing attention in the use of oxygen analysis instrument, otherwise the analysis result is not accurate and so on.Therefore, york instrument summarizes several points for your reference:
1. Before the initial operation of the oxygen analyzer, the connection point, welding spot, valve, etc. should be checked for leakage to ensure that oxygen in the air does not leak into the pipe and instrument, resulting in high measurement value.
2. Before using the instrument again, the pipe system should be cleaned and the air leaked should be blown clean. At the same time, it should be ensured that no air is leaked when connecting the sampling pipe.
3. The change of oxygen content in the sample gas will be affected by the pipe material and surface roughness. Therefore, copper pipe or polished stainless steel pipe is generally used for the connecting pipe, rather than plastic pipe or rubber pipe.
4. In micro analysis, the dead Angle of various pipe fittings, valves and meter heads should be avoided to pollute the sample air. Therefore, it is necessary to simplify the air path system as much as possible, and the dead Angle of connecting parts should be small.Power to prevent pollution caused by the release of dissolved oxygen, it is best to use water seal, oil seal and wax seal equipment to ensure accurate data.
