The Chemical Laboratory of the Saint Petersburg Technopark offers UV spectrophotometry services—an analytical method based on measuring the absorption of ultraviolet and visible light by samples.
The method allows for determining the concentration of a compound in solution, its purity, identity relative to a standard, and monitoring changes during storage, synthesis, or substance interaction. Analysis is performed both at fixed wavelengths and in full spectral scan mode.
UV spectrophotometry is applied in the development, validation, and quality control of pharmaceutical substances, organic compounds, synthesis intermediates, and reagents. Results are provided as a report with spectral graphs, optical density values, and conclusions from the Center's specialists.
