Frequently asked questions
What should be confirmed before SEM testing?
Provide the material type, specimen condition, question to be answered and any existing data. An engineer will confirm preparation, test conditions and deliverables.
How are turnaround time and specimen quantity determined?
Turnaround time and specimen quantity depend on specimen condition, test scope and analysis requirements, and are confirmed during technical review.
