Brand: Eltra | Category: Scientific & Laboratory Equipment
Impulse furnace analyser for oxygen and nitrogen in inorganic materials. Oxygen is measured as carbon dioxide by infrared absorption and nitrogen by thermal conductivity, following fusion of the sample in a graphite crucible. It suits steel and non-ferrous metal laboratories where hydrogen is not part of the specification.

Dedicated hydrogen analyser using the hot extraction method, in which the sample is heated below its melting point so diffusible hydrogen is released without fusing the matrix. It is used on steel and iron, where hydrogen content governs susceptibility to cracking.
Impulse furnace analyser configured for oxygen and hydrogen only, for laboratories that do not need nitrogen determination. Removing the nitrogen channel simplifies the gas handling and shortens the analysis, while keeping the same hot extraction principle in a graphite crucible.
Dumas combustion analyser for carbon and nitrogen, with protein calculated from the nitrogen result. It is the alternative to Kjeldahl digestion for food, feed, soil and fertiliser laboratories, and avoids the concentrated acid and catalyst that the wet method requires.
