PREP C20
COLUMN-BASED PREPARATIVE FRACTIONATION

Fully Automated Column-based Preparative
Fractionation Equipment for Polymers.
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.

KEY FEATURES
Fully automated preparative fractionation:
Up to 20 grams of polymer, depending on the sample.
Column-based fractionation.
Unlimited number of fractions (up to 9 fractions without exchanging
bottles).
No handling of hot solvents.
Subambient operation thanks to an integrated compressor (no need for
liquid coolants).
Future extension to other column-based fractionation methods:

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.

Different columns (Interaction Chromatography).
Solvent-non solvent column-based molar mass fractionation.

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.
