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
