Bruker® G4 PHOENIX

CS/OHN-Analysis (CS/ONH)

Bruker® G4 PHOENIX

Know your hydrogen value quickly to avoid embrittlement and cracking. 

There is a risk of introducing hydrogen in every mechanical, thermal and galvanic manufacturing step, especially during welding and soldering. The rapid method applied by the G4 PHOENIX can deliver results in less than 30 minutes, allowing for pre-welding testing for diffusible hydrogen unlike traditional methods that require multiple days. 

 

Benefits

Diffusible hydrogen analysis by combustion

This allows users to optimize their process to avoid costly failures, before they are done. Although high-strength steels and oxygenated copper grades are particularly susceptible to hydrogen embrittlement, an uptake of diffusible hydrogen affects many more metals; depending to a large extent on the environmental and process conditions, like ambient moisture.

The highly sensitive thermal conductivity detector allows analysis down to a sub-ppm range, while the optional mass spectrometer allows detection limits in the low ng/g range. Accurate and rapid diffusible hydrogen measurements allow you to avoid embrittlement, hydrogen-induced cracking and other costly failures.

Applications

Bruker® G4 PHOENIX hydrogen analyzer at work

Welding

Welding | Allied Processes

Bruker’s unique G4 PHOENIX is supported by ISO3690 and AWS A4.3 to enable rapid assessment of diffusible hydrogen levels introduced during welding. Because of its speed, the PHOENIX enables pre-welding experiments on test samples – helping the welding industry avoid costly failures.

High-Strength-Steels

High-Strength Steels

High-strength steels are are used in many modern assemblies and highly complex stamped-bent designs made from rolled sheets and stripes. Rolled, thermally treated, galvanized, bent, stamped, welded or coated – each step increases the chance of hydrogen embrittlement. Understanding introduced hydrogen levels can help lower the risk of crack formation.

Thermal-Desorption-Mass-Spectrometry

Thermal Desorption Mass Spectrometry

TDMS with temperature ramps provides kinetic information about trapping-energy of hydrogen within a metal structure giving terms like diffusible, weakly or strongly trapped, and chemically-bound hydrogen a direct correlation with supplied activation energy. The G4 PHOENIX MS can analyze hydrogen or isotopes like deuterium at concentrations of a few ng/g for precise mechanism investigations of alloys suitable for hydrogen storage.
