ELTRA GmbH has over 30 years of experience in the construction of elemental analyzers for the determination of the carbon, sulfur, nitrogen, oxygen and hydrogen content in solids as well as thermogravimetric analyzers.

Several analyzers have been especially optimized for fuel and energy applications and play an important role in the reliable elemental analysis of coal, coke, bio fuels, secondary fuels and oils.


carbon / sulfur analyzer CS-2000 The efficient combination of induction and resistance furnace in one analyzer (ELTRA Dual Furnace Technology) results in an economical solution for the elemental analysis of carbon and sulfur in construction materials.

In addition to the induction furnace for the elemental analysis of construction materials, the CS-d is also equipped with a resistance furnace, which allows temperatures up to 1,550°C. The resistance furnace is ideal for analyses of combustible materials like coal, coke or secondary fuels.


carbon / hydrogen / sulfur analyzer The effective calorific value of fuels depends on their respective carbon and especially hydrogen content. When secondary fuels are combusted, for example, a significant amount of water is formed from the hydrogen content, which must then be vaporized through a rotary tube furnace. This procedure significantly reduces the calorific value.

Elemental analysis and the reliable determination of carbon, hydrogen and sulfur content is therefore essential - the CHS-580 with its resistance furnace is the ideal analyzer for this task. For a high throughput of samples the CHS-580A is available with an autoloader for 36 or 130 crucibles.



thermogravimetric analyzer TGA Thermostep The conventional determination of thermogravimetric parameters such as moisture, ash or LOI (Loss On Ignition) with muffle furnaces and an external balance is in many cases time-consuming and involves high operational costs in terms of personnel.

The TGA Thermostep is a programmable thermogravimetric analyzer with an integrated balance, which determines various parameters such as moisture, volatiles and ash in fuels or the LOI in cement at user-defined temperatures and atmospheres in a single analysis.
