Fractionator / laboratory

PREP C20 is a fully automated preparative pilot plant type equipment designed to fractionate, in a column support, high amounts of polymer according to its chemical composition by a Temperature Rising Elution Fractionation (TREF) process.

A dry sample is put into a vessel and filled with solvent for dissolution. The sample solution is then loaded to a column where fractionation takes place according to the basis of the TREF technique. The system fractionates following the selected method conditions and number of fractions, which can be eluted at as many temperature levels and volumes as desired. At the end, the vessel is rinsed and ready for the following fractionation.

The main steps in the preparative fractionation process (dissolution, column loading, crystallization, elution, and fraction collection) are performed in an automatic mode, thus, avoiding the need for handling hot and large amounts of solvent. It is precisely in its capacity of fully automating fractionation of large amounts of polymer where the system holds its major benefit.

PREP C20 facilitates cross-fractionation studies (fractionation through TREF and follow up analysis through GPC/SEC), that have been demonstrated to be a necessary tool to fully characterize resins. Fractions obtained can be further analyzed by spectroscopic techniques and can be used for micromechanical testing as well.
