Due to the high sensitivity of the oxygen analyzer, it is necessary to actively carry out maintenance and upkeep during daily use. If this is not handled properly, it can easily affect subsequent work, causing disorder in the analysis results and thereby affecting its service life.
When conducting trace analysis, the gas path system should be simplified as much as possible. Especially the blind spots of various pipe fittings and valves are prone to contamination. Therefore, it is necessary to choose connection pieces with smaller corners to avoid using oil seals and wax seals-related equipment. The purpose is to prevent the release of dissolved oxygen from causing contamination, so as to better purify the cleanliness of the system and obtain accurate data.
When using an oxygen analyzer, it is necessary to strictly check whether there is any leakage in the sampling pipeline. The leaked air must be blown out completely to avoid oxygen entering the equipment through the sensor and causing corrosion. During the evolution of the pipeline system, in order to maximize efficiency, it is necessary to adopt alternate high-pressure venting or low-flow urging methods, which can also achieve faster pipeline purification.
The leakage problem of the oxygen analyzer largely affects its lifespan. Therefore, it is necessary to conduct strict inspections before startup. For critical connection points and valves, there must be no leakage. In addition, the material of the pipeline and the surface roughness will affect the change of oxygen content in the sample gas. Under normal circumstances, stainless steel pipes should be used as connection pipes, while plastic pipes and rubber pipes have aging problems and are not suitable for use.
