text: The Van Deemter equation can be further expanded to:
  Where: 
  * H is plate height
  * λ is particle shape (with regard to the packing)
  * d is particle diameter
  * γ, ω, and R are constants
  * D is the diffusion coefficient of the mobile phase
  * d is the capillary diameter
  * d is the film thickness
  * D is the diffusion coefficient of the stationary phase.
  * u is the linear velocity
