Worksheet: IR Sample Preparation

In this worksheet, we will practice describing infrared spectroscopy sampling methods including Nujol mulls, gas cells, salt plates, and compressed discs.

Q1:

What is the advantage of using a silver chloride sample cell rather than a sodium chloride sample cell for IR spectroscopy?

  • ASilver chloride does not absorb IR radiation.
  • BThere is no advantage.
  • CSilver chloride is translucent.
  • DAqueous samples can be measured; A g C l is not water soluble.
  • ESodium chloride is less expensive.
