Elemental Analysis in Medical Engineering

The materials used in medical engineering and medical products such as implants and stents are subject to rigid testing and comprehensive quality control, for example regarding elasticity or the protection from embrittlement.

ELTRA GmbH has over 30 years of experience in the construction of elemental analyzers for the determination of C, S and N, O, H in a large variety of materials. Several analyzers have been especially optimized for medical engineering and medical products.

Carbon / Sulfur Analyzer CS-800

Because the elemental content of carbon and sulfur greatly influences the hardness and workability of materials such as steel and titanium, their precise elemental analysis is important for medical products.

The powerful induction furnace of the CS-800 melts all kinds of inorganic samples in a pure oxygen atmosphere at temperatures above 2,000 °C while up to four independent infrared cells with flexible measuring ranges precisely determine the sulfur and carbon content.

Oxygen / Nitrogen / Hydrogen Analyzer ONH-2000

Hydrogen embrittlement is a significant danger in the composition of steel and titan materials. The ONH-2000 works with an impulse furnace, reaching temperatures above 3,000°C, and allows to simultaneously determine the oxygen/nitrogen or oxygen/hydrogen content with the inert gas fusion technique.

Elemental analysis in the analyzer is carried out via infrared cells and a sensitive thermal conductivity cell. A furnace with wider opening is available as an option. This guarantees reliable results, even for large samples with light weights (e.g. stents).
