Frequently Asked Questions
Technical information
Why use a dedicated analyzer?
Because gas configuration and detection is optimized for ultra-low hydrogen, increasing sensitivity.
Does the EMGA-21E measure O and N?
No. The EMGA-21E is dedicated to hydrogen. For O/N/H, select the appropriate EMGA-Expert configuration.
Can the EMGA-21E support embrittlement studies?
Yes. The quantification of H in metals is relevant to investigate and control the risk of weakening.
