COMBUSTION GAS ANALYZER – CS/ONH

G4 PHOENIX DH

The G4 PHOENIX DH, utilizing carrier gas warm extraction for a rapid and automatic determination of diffusible hydrogen in a wide variety of matrices. Thus, diffusible hydrogen is critical to assess because of embrittlement, hydrogen induced or assisted cracking (HIC/HAC) or hydrogen delayed fracture among other damaging effects. Accurate and rapid diffusible hydrogen measurements allow you to avoid embrittlement, hydrogen-induced cracking and other costly failures.

Highlights:

• Limit of Detection for Hydrogen – highly sensitive thermal conductivity detector (TCD) allows analysis down to a sub-ppm range
• 30 mm diameter of the furnace tube – suitable to accept large samples like sheet metal or welding specimen according to AWS A4.3
• 10 Volumes of the automated gas dosing calibration system – ensure linearity and traceability of your calibration over a wide dynamic range

Applications:

• Versatile for diffusible hydrogen applications for wide variety of materials i.e., steel, welds, and may others

Technical Data:

• Measuring range: 0.05 – 1000 μg/g hydrogen
