Beschreibung
Zusammenfassung:	PURPOSE: A thermal oxidation reactor for automatic measurement of nitrogen and phosphorous is provided to reduce the time for lowering the temperature after oxidization and thereby shorten the time for analysis. CONSTITUTION: A thermal oxidation reactor for automatic measurement of nitrogen and phosphorous is as follows. In order to heat and oxidize a sample at 120°C for 30 minutes, an aluminum block(10) is made by processing an aluminum ingot into a cylindrical shape. The aluminium block is punched and a glass tube(4) and a heating element(13) are fitted into the hole, thereby achieving uniform heating. The aluminium block at the boundary in contact with the glass tube is spirally carved to form a cooling coil(3) in which cooling water flows.
