Our UV-VIS Absorption Spectra service measures how chemical substances absorb ultraviolet and visible light using OECD Test No. 101. This testing helps companies understand basic optical properties that support regulatory submissions, safety evaluations, and product development.
Because light absorption can affect chemical behavior, UV-VIS data plays an important role in environmental and safety assessments. Therefore, many regulatory frameworks request absorption spectra information as part of substance characterization.
UV-VIS spectroscopy measures how much light a substance absorbs across a range of wavelengths. As a result, the test helps determine whether a substance absorbs light that could trigger chemical changes, such as breakdown when exposed to sunlight.
The test method is defined by the Organisation for Economic Co-operation and Development and is accepted worldwide. Consequently, results generated using this method are suitable for international regulatory use.
This service typically includes:
Preparation of test solutions
Measurement of absorbance across UV and visible wavelengths
Identification of absorption peaks
Review of data quality
Clear reporting aligned with OECD Test No. 101
In addition, results are checked for consistency before final reports are issued.
UV-VIS absorption testing is commonly used for:
Regulatory chemical submissions
Environmental and photostability assessments
Research and development support
Basic substance characterization
Because optical properties influence how substances interact with light, this data helps regulators and scientists make informed decisions.
Pentyl Labs provides clear and reliable UV-VIS absorption spectra testing with practical turnaround times. Moreover, we support broader regulatory and R&D programs, allowing results to fit easily into compliance and development workflows.
