Theoretical plate height and optimal mobile phase linear velocity

Function for calculation of the theoretical plate height and optimal mobile phase linear velocity

File name 'VanDeemter.m'. This function can calculate
the theoretical plate height of a chromatographic column
at different mobile phase velocities according
to the Van Deemter equation. Furthermore, the optimal
mobile phase linear velocity can be determined.

Seven input values : 'dp', 'D', 'dc', 'epsilon', 'A', 'B' and 'C'
Three output values : 'H', 'u' and 'u_opt'

INPUT
epsilon : volume fraction
dc : column diameter (m)
dp : particle size (m)
D : diffusion coefficient (m2/s)
A : A-term of the Van Deemter equation
B : B-term of the Van Deemter equation
C : C-term of the Van Deemter equation

OUTPUT
H : theoretical plate height (micrometer)
Hmin : minimal value of plate height (micrometer)
u : mobile phase linear velocity (cm/min)
u_opt : optimal mobile phase linear velocity (cm/min)


Input syntax : [H, Hmin, u, u_opt] = VanDeemter(dp,D,dc,epsilon,A,B,C)
