Raman spectroscopy in the Netherlands, Belgium and Germany
Vibrational signatures for identifying and comparing materials, phases and local structural changes. What it answers, what it cannot establish on its own, what a laboratory will ask, and how many Dutch, Belgian and German facilities publish it.
What it answers
- Which molecular or crystalline form is present — for example which carbon phase or polymorph?
- How do composition or stress vary across a map of the sample?
- Is a carbon coating or deposit amorphous, graphite-like or diamond-like?
What it cannot establish alone
- Identify every material or trace residue; fluorescence, weak Raman scattering and overlapping bands can obscure the signal.
- Determine elemental composition or a universal concentration directly from peak intensity.
- Assign a peak shift uniquely to stress without considering temperature, composition and calibration.
- Guarantee the original state of a laser-sensitive sample without controlling exposure.
Before you contact a laboratory
What a laboratory will ask.
A laboratory can say whether it can help only when these are known. Unknowns are fine; say so.
- Material, suspected phase or compound and the comparison or identification objective.
- Sample form, substrate and the size and location of the region of interest.
- Known fluorescence or laser sensitivity and any reference spectrum or control sample.
- Single spectra or a map, spatial scale and any temperature or environmental requirements.
A question a laboratory can answer
We deposit diamond-like carbon coatings on tool steel and want to compare the carbon bonding of coatings made with two process settings, five spots per sample.
