Question

Describe the purpose of the source, monochromator , detector in the double beam spectrophotometer and give two examples of each of these components

science chemistry

Answer 1

Answer #1

source : It can be UV ray, visible ray or Infrared ray

UV: It is obtained by heating filament which is filled with hydrogen or deuterium.

Visible: Incadascent lamp with tungsten filament

Monochromator: To obtain radiation of one wavelength

eg: prism,diffraction gratings

Detector: photocell or thermocouple
