Uv Vis Testing

Uv Vis Testing. UVVis is an analytical technique that measures the absorbance of visible or ultraviolet light at a single wavelength or over a spectral range By measuring the absorbance of a compound in solution and calculating the molar extinction coefficient of the compound from a standard the concentration of that material can be quantified.

The method works by measuring the amount of UV light typically at 254 nm that is able to pass through a water sample of a given path length It is defined as the ratio of the intensity of light after passing through a water sample (l) to the intensity of light at the source (l 0 ) expressed as a percentage.
