CRYSTEX instrument is considered a breakthrough technology in automation of the Xylene Solubles determination in polypropylene copolymers. The crystalline and amorphous fractions are separated through dissolution – crystallization temperature cycle within closed stainless steel vessels (up to three samples can be analyzed at a time). Accurate and precise quantification is achieved by means of an optimized infrared detector, with no need of manual volume measurements or even to use the balance at all.

A high sensitivity capillary viscometer is an ideal complement to the Infrared detector in some polyolefin characterization instruments such as GPC-IR, TREF, CEF or CRYSTEX.
Viscometer configuration is optimized to achieve a better performance in each technique.
The CRYSTEX Software has been specifically designed to control the instrument and to fully automate the Xylene Solubles analytical process so as to avoid manual handling solvents and perform the calculations directly integrating all the detectors signals.
The CRYSTEX Software is intended to be an automated alternative to the gravimetric method. It offers two modes: automated analysis and manual action; in the automated mode, an easy and complete interface defines all the conditions for the analysis, such as the temperature, crystallization ramps, time or volume. Therefore, starting a run with up to 3 samples at a time only involves putting the pellets or powder inside the crystallization vessels and starting the software. In about 4 hours, the whole analytical process will be completed, including the sample preparation and final cleaning.
Calculations can be accessed through the CRYSTEX database, which facilitates the storing and managing of all the previously analyzed samples. Results will directly provide the percentage of Xylene Solubles as well as the measured concentration by the infrared detector; hence there is no need of an accurate sample weighing before starting the process.
When additional detectors are incorporated to the CRYSTEX equipment, intrinsic viscosity results and ethylene (C2) content will be shown per sample as well, both from the parent sample and also from the amorphous phase.
The CRYSTEX Software incorporates a manual mode to be operated by advanced users or Polymer Char engineers. The manual mode becomes a powerful tool as it functions as a Virtual instrumentation interface to the instrument hardware to perform any action on any hardware element. Consequently, the user does not need to work manually at a high temperature and to handle solvents in maintenance or diagnosis tasks.
