Description
CRYSTEX® QC measures the Soluble Fraction % (amorphous fraction) in polypropylene and other polyolefin resins.
This instrument is an automated alternative to the traditional wet chemistry method based on xylene solubility, known for being time consuming and requiring constant manual handling of solvent at high temperature. CRYSTEX® QC is easy to operate and obtains the amorphous phase content in a short time. It eliminates the need to handle solvent manually and uses less flammable solvents than Xylene (TCB or oDCB), increasing the safety level in the laboratory.
The instrument automates the entire analysis process, including dissolution, separation of the soluble fraction from the crystalline matrix, and analysis by the online detectors.
Precise quantification is achieved by means of an infrared detector that also delivers ethylene content information. Moreover, the instrument measures intrinsic viscosity by means of a built-in dual capillary viscometer. All results (concentration, ethylene content and intrinsic viscosity) are obtained for the whole sample, the amorphous fraction, and the crystalline fraction.
Up to 4g of polymer can be analyzed, one sample at a time with CRYSTEX QC. For an equally automated analysis of multiple samples (up to 42), known to be homogenous (pelletized), can be performed using the same technology in the CRYSTEX® 42.
Features - Fully-automated analysis of the soluble (amorphous) fraction in polypropylene and other polyolefins.
- A sample can be analyzed every 2.5 hours (including dissolution and rinsing time) without manual operation.
- No need for accurate weighing of sample nor manual solvent handling.
- No external filtration nor solvent evaporation required.
- Additional measurement of ethylene content and intrinsic viscosity for the fraction, the crystalline fraction, and whole sample.
- For Process /QC laboratories in production plants.
- Compatible with other polyolefin materials such as LDPE, and adaptable to other solubility tests (heptane or hexane solubles).
