Now available in the US,  the ELTRA® Thermostep ML

We are delighted to introduce the ELTRA TGA Thermostep ML, a Thermogravimetric analyzer for organic and inorganic analysis. 2020 is the first time this ELTRA instrument has been available in the US.

Thermogravimetry is a standard method for the analysis of organic, inorganic and synthetic samples, in which the weight loss is measured after heating to a certain temperature.

The ELTRA TGA Thermostep is a thermogravimetric analyzer that can determine various parameters such as moisture, volatile components and ash content in one analysis. The user determines the temperature and ambient gas.

Introducing... the ELTRA® ELEMENTRAC ONH-p 2

The new ELTRA ELEMENTRAC ONH-p 2 is a powerful and robust elemental analyzer for measurement of oxygen, nitrogen and hydrogen concentrations in inorganic materials like steel, iron, copper or ceramics. The highly sensitive NDIR and thermal conductivity detectors reliably detect element concentrations from low ppm content to high percentages.

The chemicals and filters required for the operation of the ELEMENTRAC ONH-p 2 elemental analyzer are arranged conveniently on the front panel and can be concealed behind a removable door during routine operation. This arrangement significantly reduces the time required for maintenance and increases user-friendliness. In addition, innovative details considerably improve the reproducibility of measurements
