How could Hansen solubility parameter be determined ?

Question

Hansen solibility parameter is an important parameter,in order to solve a certain material in a solvent. this parameter is constructed by three component, dispersion(D), dipole(P),hydrogen(H) bonding interactions, especially, P and H is very important and need to draw the P vs. H graph.
Then, I have a quesion.
Would someone tell me how to determine Hansen parameter and R which is distance between a material and solvent by drawing P vs. H graph,
when a material(powder,solid) which Hansen parameter is not
known can be solved by some solvent(organic solvent) which Hansen parameter is known ?

Answer 1

Plot the R values onto the graph.
