Ultraviolet–Visible Spectroscopy (UV-Vis) is a widely used analytical technique that measures the absorbance or transmittance of UV and visible light by a sample. At SIMA LABS, UV-Vis spectroscopy plays a crucial role in routine quality control and research, offering rapid, non-destructive, and cost-effective analysis of compounds in pharmaceuticals, food, cosmetics, chemicals, and environmental samples.
Key Offerings:
- Quantitative analysis of active ingredients, colorants, and impurities
- Conformity to USP, BP, IP, and FSSAI protocols
- Multi-wavelength detection and scanning capability
- Custom method development for specific applications
- High-throughput screening for raw materials and formulations
