Precise element analysis

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 up to 3000 °C. The ONH series comprises analyzers for the exclusive determination of O, N or H as well as combinations for OH, ON and ONH (Fig.). ELTRA’s ONH analyzers allow for precise and fast sample analysis, covering a variety of applications including analysis of metals, ceramics and ores. The ONH series features measuring ranges which can be customized according to the user’s requirements. 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.
