Management of data and parameter files. So let's say we have two solutions that contain some type of solute. At the moment we are doing 3 tests: Control of wavelength (wavelength accuracy test), control of absorbance (photometric accuracy test) and a stray light test. Designed by the leaders in UV-Visible Spectroscopy for molecular absorption quantitative analysis, the UV-1280 Multipurpose UV-Visible Spectrophotometer offers wavelength scanning from 190-1100 nm. Most would assume that it is nothing different from Colorimeter but there is a huge difference. Since the spectrophotometer measures absorbance of light it would work the best in an experiment when we use the color light that is best absorbed by the material we are examining.
