Notes on the use of oxygen analyzers
Before using the instrument again, purify the piping system, purge the leaked air, and ensure that the sampling line is not leaking into the air.
Micro analysis, to avoid all kinds of pipe fittings, valves, headers and other dead corners on the sample gas pollution, therefore, we must simplify the gas path system as much as possible, the connection parts of small corners. The power to prevent dissolved oxygen pollution caused by pollution, it is best to use water seals, oil seals and wax sealing equipment, in order to ensure accurate data.
The change of oxygen content in sample gas will be affected by pipe material and surface roughness. Therefore, copper pipe or polished stainless steel pipe can be used in general connection line, instead of plastic pipe and rubber tube.
The oxygen analyzer shall leak check the connecting points, solder joints and valves before the initial operation so as to ensure that the oxygen in the air will not leak back into the pipe and the instrument, resulting in higher measurement values.
