UV–Visible Spectroscopy (UV–Vis)
UV–Visible spectroscopy (UV-Vis) is an analytical technique that measures how molecules absorb light across the ultraviolet and visible wavelength range. Because absorbance is directly related to molecular structure, concentration, and electronic transitions, UV–Vis provides rapid, non-destructive insight into purity, stability, reaction kinetics, and functional behavior in both liquid and solid samples.
At Materials Metric, UV–Vis spectroscopy is applied across materials science, pharmaceuticals, biomaterials, polymers, coatings, and environmental testing. Our workflows deliver reliable absorbance profiles and quantitative data supporting formulation development, quality control, degradation studies, and process monitoring.
Uses of UV–Visible Spectroscopy
UV–Vis enables quantitative and qualitative evaluation of:
- Concentration and purity of analytes
- Electronic transitions and chromophores
- Polymer degradation and oxidation
- Nanoparticle formation, aggregation, and optical properties
- Drug release and dissolution kinetics
- Reaction monitoring and rate determination
- Dye, pigment, and colorant stability
- Biomolecular quantification (proteins, nucleic acids)
It is a valuable tool for both routine QC and advanced research applications.
