Determination and detection of oxygen and nitrogen content

Material Analysis 百检检测 2024-03-14

Oxygen content refers to the oxygen content in the atmosphere、 which is generally around 21%. According to scientists' research、 if the oxygen content in the atmosphere exceeds 35%、 it is very dangerous. The atmosphere is extremely prone to spontaneous combustion、 and there is a possibility of fire on the Earth anytime and anywhere. At that time、 the Earth will become a sea of fire and a hell of life. In the international standard classification、 nitrogen content involves nonferrous metals、 analytical chemistry、 textile products、 edible oils and fats、 oilseeds、 refractories、 metal ores、 ferrous metals、 insulating fluids、 fluid flow measurement、 inorganic chemistry、 welding、 brazing and low-temperature welding、 ferroalloys、 textile fibers、 milk and dairy products、 powder metallurgy、 waste、 soil、 soil science、 water quality、 feed、 foam materials、 fuel、 leather technology Lubricants、 industrial oils and related products、 plastics、 raw materials for rubber and plastics、 sugars、 sugar products、 starch、 petroleum products、 meat、 meat products、 and other animal foods、 fertilizers、 rubber、 agriculture、 general methods for food testing and analysis、 organic chemistry
