CRYSTEX instrument is considered a breakthrough technology automation of the amorphous fraction in polypropylene copolymers, also referred to as xylene solubles measurement in polypropylene copolymers. The crystalline and amourphous fractions are separated through dissolution – crystallization temperature cycle within closed stainless steel vessels (up to three samples can be analysed at a time).
This method is being embraced by the industry as a robust and reliable alternative to traditional gravimetric method (ISO 6427 part B, ASTM D-5492) due to dramatic reduction of time spent by the analyst and laboratory supplies, the outstanding precision and the multi-detection capabilities.
Full automation of the Xylene Solubles method, no manual solvents handling
Results compatible with manual ISO 6427 method
Linear correlation with Heptane Solubles method
Results of three samples in about 4 hours
No need for accurate weighing of sample or volume control
Low consumption of solvent
Process with no user supervision required and intrinsically safe operation
Precision obtained in the Xylene Solubles results better than 0.7% RSD.
Ready for continuous operation 24 hours/7days in manufacturing control laboratories
Incorporation of the IR4 detector for measurement of concentration
Possibility of obtaining additional information : ethylene content and intrinsic viscosity of the whole polymer, crystalline and non-crystalline fractions
Remote control possibility to easy diagnosis from Polymer Char Service Centre
