Why this test

What SEM-Raman can help you understand

Correlative SEM-Raman Analysis is selected when the project needs defensible information on morphology and microstructure, molecular or crystalline Raman identity, or elemental or molecular-ion distribution across the…

Start from the question, not the instrument

The measurement mode, preparation route and reporting depth depend on what you need to learn from the sample.

Sample requirements

What to send

Provide representative, clearly labelled samples and identify the region, feature or comparison that matters.

Suitable sample or inputSubmission requirementPlanning note
Powder / particlesProvide a dry, homogeneous and clearly labelled sample in a sealed container.Exact mass and any drying or dispersion step are confirmed after technical review.
Film / coatingProvide the coated substrate or a flat film with the test surface and coating side clearly marked.State the substrate, nominal thickness and whether sectioning or mounting is permitted.
Test coupon / specimenProvide labelled specimens prepared to the agreed geometry, orientation and surface condition.Confirm the applicable standard, dimensions, loading direction and number of replicates.
Device / assemblyProvide a complete labelled device or assembly with drawings, interfaces and operating limits.Confirm power, connections, operating state, access restrictions and permitted disassembly.

Region of interest: include a marked image, sketch or reference when the target feature is localised.

Handling: declare hazardous, magnetic, volatile, moisture-sensitive, beam-sensitive or temperature-controlled material before dispatch.

Questions and answers

Common planning decisions

Short answers to issues that can change preparation, scope or interpretation.

What should I send for Correlative SEM-Raman Analysis?

Provide powder / particles, film / coating, test coupon / specimen, device / assembly as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.

Which analysis option should I choose?

Choose the mode around the decision you need to make. For morphology and microstructure, start with SEM-Raman; add SEM-Raman plus FIB cross-section when comparison or quantification is required.

How long will the test take?

Typical turnaround is 7 working days after sample acceptance and method confirmation.

What can limit the result?

Registration accuracy and different sampling depths must be considered. The complete workflow is slower and more destructive than a single technique.
