Extent: E+W+S+N.I.

Note 2 : With several reference triglycerides, it is also possible to calculate the resolution with respect to triolein:
α = RT 1 ∕ RT triolein
by use of the reduced retention time RT 1 = RT − RT solvent
The graph of log α against f (number of double bonds) enables the retention values to be determined for all the triglycerides of fatty acids contained in the reference triglycerides — see Figure 1.
