Overview
TDS thermal desorption hydrogen analyzer is a combination of diffusion hydrogen analyzer and mass spectrometer, which measures the diffusion hydrogen content in metal materials through thermal extraction method, and can also analyze the hydrogen trap binding energy in steel through hydrogen thermal desorption spectrum. The G4 Phoenix TDS analyzer can achieve programmed temperature rise and freely set the heating rate, enabling temperature measurement as well as linear and gradient heating measurement. The heating rate can be freely set.
Product Details
Brand: Brooke
Equipment Name: TDS Thermal Desorption Hydrogen Analyzer
Model: G4 Phoenix+MS
1、 Main functions and application scope:
The G4 Phoenix TDS analyzer can measure the diffusion hydrogen content in metal materials through thermal extraction, and can also analyze the hydrogen trap binding energy in steel through hydrogen thermal desorption spectroscopy. This device can achieve programmed temperature rise and freely set the heating rate. It can achieve temperature measurement, as well as linear and gradient heating measurement. The heating rate can be freely set; The software records the real-time release process curve of hydrogen as the temperature rises, and the diffusion hydrogen, non diffusion hydrogen, and total hydrogen content can be calculated through the curve; Analyze the binding energy of hydrogen traps by measuring the hydrogen thermal desorption spectrum; This equipment is mainly used for the study of hydrogen embrittlement performance of high-strength automotive steel, providing more targeted detection data for the control of hydrogen content in the production, research and application process of steel by production and R&D personnel, and providing reliable basis for the research and development of high-strength, hydrogen embrittlement resistant steel products and hydrogen embrittlement sensitivity evaluation.
