Feb 19, 2024 · In spectroscopic analysis, Near-Infrared (NIR) and Ultraviolet (UV) spectroscopy each offer distinct advantages. Near-Infrared, exemplified by NIRLAB’s handheld devices, provides rapid and non-destructive analysis for various applications, while UV spectroscopy excels in meticulous quantitative analysis in laboratory settings.

UV/VIS/NIR spectroscopy is a powerful analytical technique to determine the optical properties (transmittance, reflectance and absorbance) of liquids and solids. It can be applied to characterize semiconductor materials, coatings, glass and many other research and manufacturing materials.

Learn about the basics of UV-Vis spectroscopy, with an overview of the principle of UV-Vis, how UV-Vis spectrophotometers work, UV-Vis applications, accessories, and measurement techniques. Plus, find out how to optimize parameters for UV-Vis measurement success.

The V-700 Series of UV-visible/NIR spectrophotometers has been developed to cover every aspect of routine and research measurement, flexible, durable and easily maintained.

This review highlights in situ UV–vis–NIR range absorption spectroscopy in catalysis. A variety of experimental techniques identifying reaction mechanisms, kinetics, and structural properties are discussed.

Powerful Near Infrared (NIR) and Ultraviolet / Visible (UV-VIS) spectroscopic techniques are used in our GUIDED WAVE™ NIR & UV-VIS Process & Lab Analyzers and optical solutions.

UV-Vis-NIR spectroscopy works by shining specific wavelengths of light at a material and recording the intensity of the light that reaches a detector behind it, known as trans-mittance.

Summary UV-Vis/NIR spectroscopy probes the absorption, transmission, and reflection of solid, liquids, films, and powders between 190 3200 nm. Double beam instruments use a reference beam to account for fluctuations in light intensity, to provide accurate measurements when ratioing the transmitted to incident light.
