[0002] Air separation nitrogen is nitrogen obtained by separating oxygen and nitrogen molecules in the air. When air separation nitrogen is produced, an online gas trace oxygen analyzer in the air separation industry can be installed at the outlet of the nitrogen production pipeline of the air separation equipment to detect the trace oxygen concentration in the gas produced by air separation. The trace oxygen analyzer uses a completely sealed fuel pool oxygen sensor, which is one of the most advanced oxygen measurement methods in the world. The fuel pool oxygen sensor is composed of a highly active oxygen electrode and a lead electrode, immersed in a KOH solution. The oxygen at the cathode is reduced to hydroxide ions, while the lead at the anode is oxidized.
