Gas analyzer, spectrometers

Gas analyzer "ELTRA" ОН900

Gas analyzer "ELTRA" ОН900 (GmbH ELTRA, Germany) is used to define the content of hydrogen and oxygen in zirconium, titanium, hafnium, aluminum, copper, steels and alloys, ceramics and other materials. The range of H and O content measurement makes up 0.0001 – 5.0 % (mass fraction).

Spectrometer "Spectroflame Modula S"

Emission plasma spectrometer "Spectroflame Modula S" (Germany) is used for quantitative analysis of water solutions of various materials (more than 70 elements). Scanning field-emission spectrometer with inductive coupled plasma "Spectroflame Modula S" is equipped with two monochromators: vacuum (160-460nm, reverse dispersion 0.55nm/mm) and air (240-790nm, reverse dispersion 1.1nm/mm). It allows identification of up to 70 elements in the material, the spectrum range being wide.
