Questions and Answers

In linear chromatography, what type of peak is observed as a result of the separation?

  • Exponential peak
  • Rectangular peak
  • Triangular peak
  • Gaussian peak (correct)

What is the equation for the distribution constant (K) in chromatography?

  • K = CS - CM
  • K = CM/CS
  • K = CS * CM
  • K = CS/CM (correct)

What is the equation for the average linear velocity of solute (V')?

  • V' = L / tR (correct)
  • V' = tR / L
  • V' = L * tR
  • V' = L - tR
