UV-Vis testing (ultraviolet–visible spectroscopy) is an analytical technique based on the interaction between light and matter. When ultraviolet or visible light passes through a sample, the valence electrons of its molecules undergo energy transitions. Different chemical structures exhibit characteristic absorption, transmittance, or reflectance behaviors at specific wavelengths. By recording the intensity changes of these optical signals, a spectrum across the 200–800 nm range can be obtained. This spectral profile reflects not only the electronic structure of the molecules but also provides insights into conjugated systems, functional group distributions, and substituent effects. According to the Beer–Lambert law, absorbance is linearly related to concentration, making UV-Vis spectroscopy suitable for both qualitative analysis (such as identifying molecular features) and quantitative analysis (such as precisely measuring the concentration of a component in solution).
We offer the following UV-Vis testing services to support precise analysis of your samples' optical properties.
