Molecular weight of polypropylene with GPC/SEC at high temperatures
Gel permeation chromatography (GPC), a.k.a. size exclusion chromatography (SEC), of polymers using either a refractive index (RI) detector or a multi-angle light scattering (MALS) detector.
This product is suitable for polypropylene or polyolefin polymers that are only soluble at high temperatures in 1,2,4-Trichlorobenzene (TCB).
This technique will measure the molecular weight distribution of polypropylene (PP) samples in a graphical format, the dispersity, Đ, and determine the molecular weight averages, Mn, Mw, and Mz.
Opting for the method with RI detectors will determine the molecular weight relative to a calibration standard. Please note that the numerical values determined for molecular weight by the RI method are not absolute.
Opting for the MALS method will determine the true molecular weight of the sample.
The choice of detector for the analysis will affect the cost. Please contact our experts for a quote tailored to your needs.
