UV-Vis White Papers
Olive Oil Quality Assessment with UV-Vis Spectrophotometry
UV-Vis spectrophotometry is a simple and efficient technique for the analysis and evaluation of the quality of olive oil. Extra virgin, virgin, and lower-quality olive oils can be distinguished by measuring their absorbance at four UV wavelengths. The full UV-Vis absorption spectrum provides valuable qualitative and quantitative information when oil adulteration is suspected.
Characterization of SERRS Nanoparticles Using UV-Vis and Raman Spectroscopy
Surface-enhanced resonance Raman scattering (SERRS) is a technique that offers unparalleled sensitivity and specificity in nondestructive spectroscopic detection. It combines surface-enhanced Raman scattering (SERS) and resonance Raman spectroscopy...
UV-Vis Spectroscopy for Characterising the Optical Properties of Gold Nanoparticles
UV-Vis spectroscopy is routinely used in analytical science in part because it is a simple way of studying a sample’s optical properties over the UV and visible regions of the electromagnetic spectrum. Here, we used the DS5 UV-Vis Spectrophotometer...
Working with your benchtop spectrometer at high and low sample cuvette temperatures
Spectroscopy labs are home to spectrometers of varying types: UV-Vis-NIR absorbance, fluorescence, and circular dichroism, for example, all sitting on benches at room temperature. When a scientist wants to measure spectral properties of a sample at...
Measuring Optical Densities Over 10 Abs on the Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS)
High blocking optical filters deliver critical optical control in a wide variety of consumer and industrial products. Highly attenuating (i.e., high optical density) filters are used in personal protective equipment, such as laser safety eyewear,...
