Instrumentation of UV or Visible Spectroscopy

INSTRUMENTATION

Instruments for measuring the absorption of U.V. or visible radiation are made up of the following components;
1. Sources (UV and visible)
2. filter or monochromator
3. Sample containers or sample cells
4. Detector

1. Radiation source
It is important that the power of the radiation source does not change abruptly over its wavelength range.

Analytical Aspects of Absorption Spectroscopy, (UV and Visible Spectroscopy)

The word spectroscopy is derived from spectrum which means a bend of different colours formed due to difference in wavelength and skopin means examination or evaluation.

Thus, spectroscopy is the branch of science that deals with the examination or evaluation of spectrum.
