Question: What is the primary function of a chromatographic column?

Options:

  1. To mix the sample with the mobile phase
  2. To provide a surface for separation
  3. To detect the analytes
  4. To control the temperature

Correct Answer: To provide a surface for separation

Solution: 

The primary function of a chromatographic column is to provide a surface for separation of components based on their interactions with the stationary phase.

Questions & Step-by-Step Solutions

What is the primary function of a chromatographic column?
  • Step 1: Understand that a chromatographic column is a tube used in a laboratory.
  • Step 2: Know that the column contains a material called the stationary phase, which does not move.
  • Step 3: Recognize that a mixture of substances is introduced into the column.
  • Step 4: Learn that as the mixture moves through the column, different components interact with the stationary phase in different ways.
  • Step 5: Realize that these interactions cause the components to separate from each other as they travel through the column.
