UV/VIS Absorbance Spectroscopy

Absorbance spectroscopy performed in the ultraviolet and visible light range is a highly versatile measurement technique that is incredibly popular in analytical chemistry, among many other useful applications.

The principle behind UV/VIS absorbance is the Beer-Lambert law which states that the light absorbed by a sample is in direct proportion to the concentration of that sample. Using reference data, this method enables both quantitative and qualitative measurements for a wide range of uses from blood parameters to chemical composition analysis.

The typical UV/Vis system requires a spectrometer, light source, fiber optic cable, and a sampling accessory, however, Avantes’ modular platform allows us to design the ideal system to include either a single broadband instrument or several working in tandem at different wavelengths. Avantes offers options to deliver nearly any measurement w

Applications of UV/VIS Spectroscopy

There are numerous applications that might use UV/VIS spectroscopy from analytical chemistry in the pharmaceutical industry to monitoring volatile organic compounds responsible for ground-level air pollution, and even in the production of colloids and nanoparticles whether you need high-resolution, high-sensitivity, cooled or uncooled instruments.
