Chapter 20: Q1P (page 525)

Describe the role of each component of the spectrophotometer.

Short Answer

Expert verified

Spectrophotometer: It is an optical instrument that measures intensity of light in relation to the wawelength.

Step by step solution

01

The components of spectrometer along with their roles are as followes:

  1. Light source: Gives ultraviolet, infrared, or visible radiations.
  2. Monochromator: Dispersion of light on one or more prisms or diffraction gratings at its constitutive wavelengths
  3. Beam chopper: Directs light to the sample or reference sample.
  4. Cuvet: Holds the sample
  5. Reference cuvet: Contains pure solvent or a reagent.
  6. Blank detector: Produces an electric signal when it is struck by photons
  7. Amplifier: Increase the detector signal
  8. Display: shows the result.

Consider a planar waveguide used for attenuated total reflection measurement of a film coated on one surface of the waveguide. For a given angle of incidence, the sensitivity of attenuated total reflectance increases as the thickness of the waveguide decreases. Explain why. (The waveguide can be less than1μmthick.)
