Questions and Answers

What is the purpose of preparative chromatography?

  • To separate components for further use or study (correct)
  • To identify the constituents of the mixture
  • To analyze the interactions of the mobile and stationary phases
  • To determine the partition coefficient of the mixture

    • What is the role of the mobile phase in chromatography?

  • Interacting with the stationary phase
  • Carrying the mixture through the system (correct)
  • Causing differential partitioning
  • Determining the retention time of the constituents

    • How are constituents separated in chromatography?

  • Based on their differential retention on the stationary phase (correct)
  • By their affinities for the solvent
  • By altering the partition coefficient of the mixture
  • Through interactions with the mobile phase
