Using the solution of [AB] from the quadratic equation 12 all remaining concentrations can be calculated according to the massbalance equation. The resulting equations for 1:1 models used in SupraFit are summarised in Table with only the shifts of the host and the complex are taken into account. Signals of component B are ignored. For UV/VIS this holds true if the component is not UV/VIS active at the selected wave length.
