Why this service
What Raman can help you understand
Raman Spectroscopy (Polarised / Mapping / Confocal / In-situ) is selected when the project needs defensible information on vibrational bands and material identity, phase, crystallinity, stress, or…
Phase, crystallinity, stress, or disorder
mapping or confocal depth profiling
Spatial chemical distribution
polarised, variable-temperature, or in-situ Raman
Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.
Point spectrum
vibrational bands and material identity
- Best used when
- vibrational bands and material identity
- Typical result
- Raman spectra
- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Mapping or confocal depth profiling
phase, crystallinity, stress, or disorder
- Best used when
- phase, crystallinity, stress, or disorder
- Typical result
- Peak positions, widths, and assignments
- Preparation note
- State the substrate, nominal thickness and whether sectioning or mounting is permitted.
Polarised, variable-temperature, or in-situ Raman
spatial chemical distribution
- Best used when
- spatial chemical distribution
- Typical result
- Optional confocal depth scan, polarisation series, or chemical map
- Preparation note
- State the fibre type, orientation and whether cutting, bundling or mounting is acceptable.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Raman spectra reported with the agreed units, sample reference and measurement conditions.
Peak positions, widths, and assignments supplied in a labelled format suitable for direct sample or condition comparison.
Optional confocal depth scan, polarisation series, or chemical map provided with the processing basis and quality checks agreed during technical review.
Processed spectra included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Powder / particles | Provide 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 / coating | Provide 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. |
| Fibre / textile | Provide clean, dry fibres or a representative textile section in protective packaging. | State the fibre type, orientation and whether cutting, bundling or mounting is acceptable. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What should I send for Raman Spectroscopy (Polarised / Mapping / Confocal / In-situ)?
Provide powder / particles, film / coating, fibre / textile, liquid / solution 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 vibrational bands and material identity, start with point spectrum; add mapping or confocal depth profiling when comparison or quantification is required.
How long will the test take?
Typical turnaround is 5 working days after sample acceptance and method confirmation.
What can limit the result?
Fluorescence can overwhelm Raman scattering. Laser heating and local sampling can change or misrepresent heterogeneous materials.
