Refractive Index (RI) Analysis Service
- Samples should be clean and free of suspended particles or bubbles that could interfere with optical measurements.
- Liquid samples should be sealed to prevent evaporation or compositional changes, while solid samples must be kept dry and intact.
- Clients are encouraged to provide relevant background information, including solvent system, concentration, source, and research purpose.
Refractive index (RI) is a fundamental physical parameter describing how the speed of light changes as it travels through a medium, defined as the ratio of the speed of light in vacuum to that in the material. RI not only determines the path of light propagation but also correlates closely with the molecular structure, concentration, temperature, and wavelength of the sample. Even subtle variations in RI can reveal differences in composition, purity, or structural features, making it an essential tool in pharmaceutical development, food quality assurance, cosmetic formulation research, chemical materials engineering, and environmental science.
In modern analytical sciences, RI serves as a critical parameter for optical characterization. Particularly in light scattering–based particle size determination methods such as laser diffraction and dynamic light scattering, precise RI values greatly enhance the accuracy and reliability of particle size analysis. Leveraging advanced detection platforms and a team of experienced professionals, MtoZ Biolabs provides Refractive Index (RI) Analysis Service to deliver accurate and reproducible RI measurements, supporting both fundamental research and industrial applications.
