What kind of samples can Raman spectra be used to analyze?

Launch:2019-08-14     browse:1565752989times

Raman spectroscopy can be used to analyze many different types of samples, usually including the following categories:

Solids, powders, liquids, gels, ointments and gases;

Inorganic materials, organic materials and biological materials;

A pure substance, mixture, or solution;

In general, Raman is not suitable for analyzing metals and their alloys.


Typical examples of current Raman spectroscopy applications include:

Art and archaeology -- characterization and identification of pigments, ceramics, and gems;

Structure, purity, defect/disorder characterization of carbon materials -- carbon nanotubes;

Chemistry - structure, purity, reaction monitoring;

Geology - mineral identification and distribution, inclusions, phase transitions;

Life sciences -- characterization of individual cells or tissues, drugs, disease diagnosis;

Pharmacy-drug composition uniformity and composition distribution;

Semiconductor -- purity, additive composition, stress.
