GB/T 14265 metal materials, hydrogen, oxygen, nitrogen, carbon and sulfur analysis methods General
3 method summary
In the presence of flux, the oxygen flow in the high-frequency induction furnace, so that the sample is burned at high temperatures, sulfur generated sulfur dioxide gas into
Infrared absorption cell, the instrument automatically measures its absorption of infrared energy, calculate and display the results. The method used in the analysis of principles and used
Materials and equipment are in line with the provisions of GB/T 14265.
4 material
4.1 combustion gas, oxygen, volume fraction > 99.5%.
4.2 Dynamic gas. Compressed gas, outlet pressure > 0.4MPa.
4.3 flux low-sulfur pure iron, pure tungsten 0.5gFe 1.5gW (sulfur blank value of less than 0.0005%).
4.4 Crucible Ceramic crucible (sulfur blank value of less than 0.0005%), before use should be at 1200 ℃ for more than 20min, after cooling take
Put in the dryer spare.
4.5 Standard samples.Sulfur content of 0.005% ~ 0.06%, and the sample content of the standard sample.
5 instruments
High-frequency infrared carbon and sulfur analyzer, the instrument parameters should meet the following requirements.
