Raman testing is a non-destructive analytical technique first discovered by Indian physicist C.V. Raman in 1928. It relies on the interaction between laser light and molecular vibrations to produce scattered light, most of which is elastically scattered, hile a small fraction undergoes energy shifts, orming inelastic (Raman) scattering. Each molecule and chemical bond exhibits characteristic vibrational modes, and the resulting Raman spectrum acts as a unique "fingerprint" that reveals the chemical composition and molecular structure of the sample. By analyzing these spectral peaks and intensities, R&D and industrial teams can identify molecular types, chemical bonds, and intermolecular interactions. Raman testing is suitable for solids, liquids, films, and composite materials, providing reliable structural and compositional insights to support product development, materials optimization, and quality control.
We offer the following Raman testing services to support precise analysis of material and sample structures.
Standard Raman Testing uses monochromatic laser excitation to detect inelastic scattering from samples. Both dispersive (grating) and Fourier-transform (FT Raman) instruments are available, with FT Raman offering improved fluorescence suppression. Ideal for material structure analysis, polymer characterization, and rapid solid or liquid sample testing.
Resonance Raman Testing significantly enhances Raman signals when the laser wavelength matches electronic transitions. It is suitable for high-sensitivity detection of biological macromolecules such as pigments and hemoglobin, as well as metal complexes, providing precise compositional and structural insights.
Surface-Enhanced Raman Testing employs metal nanostructures, typically gold or silver, to create strong electromagnetic fields, increasing Raman signals by 106–108 times. It is widely used for trace chemical detection, drug residue analysis, food safety, and rapid on-site sample identification.
Non-linear Raman Testing includes CARS, SRS, and time-resolved Raman, utilizing non-linear light interactions to improve signal-to-noise ratios and imaging speed. Applications include tissue imaging, chemical kinetics studies, and real-time monitoring of live cells in research and industrial contexts.
Spatially Offset Raman Testing enables non-destructive analysis of deep or encapsulated samples by offsetting the laser excitation from the measurement point. This method is ideal for examining tablet interiors, packaged materials, and other samples where surface measurements are insufficient.
Transmission Raman Testing collects Raman signals transmitted through samples, making it suitable for thick or bulk materials. It is extensively applied in pharmaceutical quality control, industrial raw material inspection, and situations requiring rapid volumetric analysis of solid samples.
