SOLUBLE FRACTION ANALYZER FOR POLYPROPYLENE PLANTS

Reliable and fully automated instrument for
Soluble Fraction determination in Quality Control
laboratories of Polypropylene plants.
CRYSTEX QC is a step forward in technology for automation
of Soluble Fraction determination (amorphous fraction) in
polypropylene resins. This is a reliable instrument for continuous
operation in the manufacturing plant laboratory with minimum
bench space and utilities requirements.
®

CRYSTEX QC overcomes all difficulties of the gravimetric
methods based on xylene solubility and traditional wet
chemistry. It eliminates sample weighing, external filtration or
extraction devices, and all the associated tedious manual
operations. Unlike other semi-automated approaches, no
handling of any solvent by the operators is required.
®

A representative amount of sample (2 to 4 grams) is put by the
operator in a 260mL disposable bottle without the need of
accurate weighing. The instrument automates all the analysis
process, including precise dosing of the 200mL solvent volume,
sample dissolution, separation of soluble fraction from the
crystalline matrix, and analysis by the online detectors.

KEY FEATURES
Samples can be analyzed every 2 hours (including dissolution and
rinsing time).
Full automation of Soluble Fraction measurement.
No need for accurate weighing of sample or manual solvent handling.
No external filtration or solvent evaporation required.
Built-in IR4 detector for accurate quantification of fractions and their
ethylene content in the case of copolymers.
For Process/QC laboratories in production plants.

The crystalline and amorphous fractions are separated through
a crystallization and re-dissolution temperature cycle within a
proprietary TREF column. Temperature is monitored and
controlled accurately at all key points. Precise quantification is
achieved by means of an infrared detector, so no analytical
balance is used with CRYSTEX QC.

The entire analytical process takes 2 hours starting when the
sample is put in the vial up to final results, being ready once
again for consecutive sample analyses.
Fully-automated analysis of multiple samples (up to 42) known
to be homogenous (pelletized) can be performed using the
same technology in the new CRYSTEX 42, but with samples
that weigh up to 300 mg.
