Analýza kyslíku dusíku vodíku


Oxygen, nitrogen and hydrogen strongly influence the properties of metals (like steel, titanium, copper) which makes a reliable and precise measurement of these elements an important part of the quality control process. ELTRA supplies analyzers for the determination of the single elements O, N, H as well as combined solutions for analyzing ON, OH or ONH.

ELTRA analyzers use inert gas fusion. This method involves heating the sample in an impulse furnace which is capable of reaching temperatures in excess of 3,000 °C. The sample is melted in a graphite crucible, oxygen is determined by non-dispersive infrared cells as CO2, nitrogen and hydrogen by a thermal conductivity cell. Typical samples for ONH analysis are metal alloys (steel, copper, refractory metals) as well as ceramics and other inorganic materials. The H-500 is available exclusively for the determination of hydrogen based on hot extraction analysis.
