For solvent mixtures of different organic solvents, the constant can be calculated by adding
the constants of the different solvents in relation to their percentage in the mixture.
For example: 50% H
2
O, 20% Methanol, 30% Acetonitril
F = 0.5 F(H
2
O) + 0.2 F (Methanol) + 0.3 F (Acetonitril)
F = 0.5 x 1 + 0.2 x 0.63 + 0.3 + 0.68
F = 0.83
For other solvents with an unknown factor, an average factor of 0.70 can be used. The
difference from the correct delivery rate won't be higher than 5%. If this accuracy is good
enough, a medium factor of 0.70 for all organic solvents and 1.00 for water can be used.
