Bruker G4 PHOENIX Diffusible Hydrogen Analyzer (G4-PHOENIX)

The Bruker G4 PHOENIX Diffusable Hydrogen hot extraction analyzer is the best solution for accurate and rapid diffusible hydrogen measurement used in assessing metals potential to become brittle through hydrogen-induced cracking.

How It Works

The G4 PHOENIX DH uses the carrier gas hot extraction method, enabling a fast and automatic determination of diffusible hydrogen in a wide variety of matrices. A sensitive and long-term stable thermal conductivity detector (TCD) detects the evolved hydrogen. With 10 different volumes, the automatic gas dosing unit guarantees simple and reliable calibration. 

Rapid Heating Furnace for Large Samples

The G4 PHOENIX is equipped with a quick heating (and cooling) infrared-heated clamshell furnace (up to 900°C). The quartz tube measuring 30 mm in diameter allows the analysis of large steel strips and weld coupons per IOS 3690 and AWS A4.3. The furnace is capable of using temperature programs and ramping to assess information about different forms of trapped hydrogen.

Residual Hydrogen at Higher Temperatures

If you need higher temperatures to analyze diffusable hydrogen as well as residual hydrogen, e.g. in steel, the G4 PHOENIX DH can be equipped with an additional wire-heated tube furnace, which can reach temperatures up to approximately 1100°C.

Thermal Desorption Mass Spectrometry

The revolutionary new technique of coupling a mass spectrometer to the carrier gas hot extraction analyzer G4 PHOENIX DH improves the limit of detection by more than one order of magnitude compared to a TCD and enables the determination of ultra-low hydrogen concentrations, e.g. in high strength steels. In addition to adding selectivity, e.g. for isotopic species like deuterium, this Thermal Desorption Mass Spectrometry (TDMS) technique provides kinetic information about the diffusible hydrogen when used in conjunction with different heating rates. 

Intuitive Software

The software that the G4 PHOENIX uses is intuitive and offers an easy-to-navigate user interface. Setting up different workflows and tasks like measurement, method setup, calibration and data evaluation, is simple as the interface is neatly divided into different views ensuring a user-friendly and efficient experience.
