How a UV-Vis Spectrophotometer Works When incident light hits an object, it can be absorbed, reflected, or transmitted. The spectrophotometer measures the intensity of light absorbed across the UV and Vis ranges. Light transmitted through the sample is measured and compared to a reference measuremen...
If that was good enough for the space program, it should be good enough for beverage analysis. For additional resources on UV-VIS spectrophotometers, including useful articlces and a list of manufacturers, visit www.labmanager.com/UV-VIS ...

trap, print contrast, hue error, greyness, saturation, cast, brightness and dot analysis. Using i1Pro-2 Photo spectrophotometer we are able to read accurate Pantone colour references so as to simplify spot colour standardization as per client's requirements, no matter what stock we print on. ...
The spectrophotometer measures how much of the light is absorbed by the sample. The intensity of light before going into a certain sample is symbolized by I0. The intensity of light remaining after it has gone through the sample is symbolized by I. The fraction of light transmittance is (I...
Transmittance measurements:Evaluation of product absorbance was performed by means of a spectrophotometere. Before measurements, the transmittance analyzer was validated and controlled according to in vitro UVA-PF procedure by both specified standardsfand the linearity/add...
