Cryogenic Diffusible Hydrogen Analyzer ESCO-TDS-100 Cryo H2|L-TDS Low-Temperature TDS (L-TDS): Unlocking the Core of Hydrogen Embrittlement and Delayed Fracture
Hydrogen trapped in lattice defects—such as dislocations and atomic vacancies—has long been recognized as a critical driver in the hydrogen embrittlement (delayed fracture) of high-strength steels.
However, due to its highly volatile and transient nature at ambient temperatures, its precise analysis has remained notoriously difficult.
Currently under development, the ESCO-TDS-100 Cryo H2 addresses this long-standing challenge. By enabling precise, controlled linear heating starting from as low as −100°C,
the system clearly separates and extracts these elusive hydrogen states with high resolution.
Furthermore, engineered with meticulous and comprehensive anti-frost countermeasures, the system reliably captures the "true hydrogen desorption profile" without moisture-induced noise, serving as a powerful catalyst
for fully unraveling the fundamental mechanisms of hydrogen embrittlement.
