ELTRA’s ONH analyzers determine the oxygen, nitrogen and hydrogen content of inorganic sample materials using inert gas fusion in an impulse furnace with temperatures of more than 3,000 °C. The ONH series comprises analyzers for the exclusive determination of O, N or H as well as combinations for OH, ON and ONH.

The ONH series features measuring ranges which can be customized according to the user’s requirements, offering extremely flexible solutions highly suitable for quality control applications in the laboratory. Measuring ranges of the ONH analyzers comprise lower ppm levels up to 2 % for 1 g of sample material. Results are obtained quickly and with high accuracy. Analyzing a steel sample, for example, only takes about 2 minutes, including outgasing the graphite crucible.

ELTRA’s ONH analyzers are suitable for a variety of applications including analysis of metals, ceramics and ores.
