UV-Vis spectrophotometry is a powerful analytical technique used in various scientific fields to measure light absorbance across the electromagnetic spectrum’s ultraviolet (UV) and visible (Vis) ranges. By measuring the intensity of light passing through a sample solution and comparing it to the inte...
A spectroradiometer is a device designed to measure the “absolute radiation” energy emitted by a light source. This energy could possibly include the entire light spectrum: visible light, UV light, and infrared light. “Absolute” means measuring the source of light with no light leakage (d...

**WHAT IS SPECTRUM? Spectrum: Rainbow like series of colors, in the order violet, blue, green, yellow, orange, and red, produced by splitting a composite light, such as white light, into its component colors. * WHAT IS UV-VIS SPECTROSCOPY? Ultraviolet-Visible spectroscopy or Ultraviolet-Visi...
The infrared spectrophotometer, often known as anIRspectrophotometer, uses infrared light to cause movement in the bonds of organic molecules. Infrared light falls between visible light and microwave radiation on the electromagnetic radiation spectrum. This type of light can be further divided into the ...
A stylised layout of a basic single beam spectrophotometer is shown in Figure 4. It comprises a white light source which is usually either a combination of a deuterium arc lamp to cover the UV range and a tungsten halogen lamp to cover the visible; or a single Xenon arc lamp to cover th...
UV light has a shorter wavelength, higher frequency and higher energy than the light within the visible spectrum. Wavelength is the size of the wave, or the distance between two corresponding points on waves – peak to peak or trough to trough, for example. The frequency is the number of ...
What is the difference between nanodrop and UV spectrophotometer? And which one is preferable for measuring the concentration of extracted DNA/RNA? Beer lambert law: The law states that the absorbance of a sample (DNA/RNA/protein...
What is the principle behind a UV visible spectrophotometer? What is the photon theory of light? Does light follow the superposition principle? What are the laws of reflection of light? What is the Huygens-Fresnel principle? What type of light is typically needed to cause the photoelectric effec...
Followingfixation, the tissue sample is transferred to a tissue cassette. These cassettes, which come in various sizes, hold and protect the tissue while it undergoes processing. Trust Your Quantification with the DeNovix DS-8X Rapid Eight Channel, 1µL UV-Vis Spectrophotometer ...
