Chemical Testing and Analysis: materials identification; analysis of metals, polymers, and ceramics; identification of contaminants; compliance of certifications; corrosion analysis and more.

Failure Analysis: fatigue; fracture; cracking; corrosion; loss of strength; bending; debonding; weld failure; braze failure; solder failure and more.

Mechanical Testing and Analysis: metal and plastic strength; custom fixturing for testing finished parts; tension; compression; bending; peel strength; tear strength; elongation and more.

Metallography: opaque object microscopy; coating thickness; plating analysis; case hardness and depth; grain size; corrosion analysis; heat treat verification; fracture morphology and more.

Professional Services: material selection; reverse engineering of competitor's products; failure prevention; material processing problems; welding and weld repair analysis; extent of fire damage to steel structures; fracture analysis; fact witness and more.
