EAG XRD crystalline joint-phase service

Eurofins EAG Laboratories · Engineering measurement and characterization

Purpose: Identify crystalline phases in representative joint materials to complement cross-section and fracture-location evidence.
Technical approach: Compare X-ray diffraction patterns with phase references; thin-film or microdiffraction configurations depend on the sample.
Scope of use: Documented for crystalline powders, films and parts; local IMC detectability depends on content, sampling and signal.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Minor or small phases may be undetectable. XRD does not directly locate fractures, provide depth profiles or identify amorphous-component chemistry.
What to prepare
BLNKK suggests preparing materials, thermal histories, suspected IMC and fracture/cross-section evidence with representative controls.
Confirm with the supplier
Confirm sample geometry, microbeam/grazing-incidence options, references, practical detectability and correlation with cross-sections.
Public evidence: EAG's service page and three-page note revised in 2023 describe phase, texture and measurement limitations.
