How can each component of Hansen's solubility parameters be determined experimentally?

23 October 2023 1 10K Report

I would like to know how all Hansen solubility parameters were determined in the beginning.

Dear Elise Mathouillot. To determine the solubility parameter, gas chromatography is used, in particular IGC SMS chromatograph (Surface Measurement System, iGC-SMS Ltd.) equipped with a flame ionization detection (FID) system.

Best regards, Pavel Yudaev.
