UV-Visible absorption spectroscopy proves to be a potent analytical technique applicable across routine and research analyses. This method hinges on the sample capability to absorb light within the UV-Vis region of the electromagnetic spectrum. By utilizing the Lambert-Beer law and by choosing a suitable optical path length it is possible to perform quantitative analyses. As a potential application, our research team performs colorimetric analyses on water samples to detect heavy metals.
