Hydrogen analyzers are used to determine the concentration of hydrogen in an unknown gas mixture. Typically, the gas will flow through a sensing chamber and be sealed in for measurement by an electronic circuit which distinguishes the difference of the thermal conductivity in comparison to a reference gas. Some hydrogen analyzers also come with the ability to analyze the concentrations of other common gases such nitrogen or oxygen.

| Description | The 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 lowThe 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 innovative sample port system with pulsed chamber rinsing and vertical sample drop allow for user-friendly and comfortable analysis of rod-shaped, granular or powdery samples with a weight of up to 2 grams.
The ELEMENTRAC ONH-p 2 elemental analyzer meets or exceeds the requirements of all relevant international standards such as ASTM E 1019 or DIN EN 3976....

ELTRA’s 580A analyzers (A = Autoloader) are equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention. The ELTRA‘s CHS-580A is the ideal analyzer for the simultaneous determination of carbon, hydogen and sulfur in organic samples. ELTRA’s 580A analyzers (A = Autoloader) are equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention. The sample loader is available in two versions to accommodate 36 or 130 crucibles. The CHS-580A is based on the technology of the CHS-580 analyzer and features a vertical resistance furnace with ceramic tube. The temperature can be set in steps of 1 °C to a maximum of 1,550 °C. Thanks to sample weights of up to 500 mg and more even inhomogeneous materials can be reliably analyzed. The analyzer can be equipped with up to three independent infrared cells according to the user’s requirements, allowing for a great variety of applications....
