Trial #0
Utilize the standard 24-solvent HSPiP panel as well as two comparatives to evaluate options for dissolution of the client's proprietary polymer
24 scintillation vials were filled with 15 mL of solvent from the TURI HSP solvent panel in addition to two other vials containing N-methyl pyrrolidone and Methyl Ethyl Ketone, these functioned as comparatives as they are currently utilized by the client in this process. Visual observations were taken prior to the immersion of the polymer sample into the solvent, then for the first hour observations were taken every 10 minutes.
