Quantitative Analysis of Low-concentration Hydrogen Content in Titanium Alloy

Can we perform quantitative analysis of hydrogen in a titanium alloy to prevent hydrogen embrittlement?

Customer needs

Titanium (Ti) alloy is used for applications in aircraft, medicine, and other fields due to its light weight, high strength, high corrosion resistance, high biological compatibility, and other properties. However, because titanium materials tend to store hydrogen (endothermic reaction), material design and production control must be implemented for preventing hydrogen embrittlement.

For this reason, customers asked us for a technique for quantitative analysis of hydrogen content in titanium alloys on a scale of several ppm to several tens of ppm.

Solved by EMGA-921!

It takes only a few minutes for quantitative analysis of low-concentration hydrogen content in Titanium alloys!
