Gas analyzer / hydrogen / benchtop / high-performance

The G4 PHOENIX DH hot extraction analyzer is the right solution for accurate and rapid diffusible hydrogen measurement to avoid embrittlement, hydrogen-induced cracking and other costly failures.
The G4 PHOENIX DH, utilizing the carrier gas hot extraction method, enables a rapid and automatic determination of diffusible hydrogen in a wide variety of matrices. The analyzer is equipped with a rapid heating (and cooling) infrared-heated clamshell furnace (up to 900°C). The quartz tube diameter of 30 mm enables the analysis of large samples like steel sheet strips as well as weld coupons according to ISO 3690 and AWS A4.3. The versatile infrared furnace also enables the use of temperature programs and ramping to assess information about different forms of trapped hydrogen.
For higher temperatures, especially for the determination of diffusible 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 be operated at temperatures up to about 1100°C.
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 hygrogen concentrations e.g., in high strength steels. Beside of 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.
