In this webinar the main separation techniques for analysis of distributions in polyolefins will be reviewed, with a special focus on the two basic pillars in polyolefin characterization: Molar Mass Distribution by high-temperature gel permeation chromatography (HT-GPC) with infrared (IR) detection and Chemical Composition Distribution (CCD) techniques by CEF, CRYSTAF or TREF, especially important in polyolefin copolymers or blends.
Once those basic pillars are covered, bivariate distribution techniques provide a higher-level knowledge through 3D results that combine Molar Mass with Chemical Composition in a single experiment, such as CFC or SGIC 2D, delivering the full picture of the polyolefin microstructure.
Alejandro Fernández has a Master’s Degree in Chemical Engineering from the Polytechnic University of Valencia, Spain. At university, he combined his studies with his passion for traveling, spending one year at the University of Bologna (Italy) and finishing his degree with a six-month stay at the University of Massachusetts Amherst (USA).
Having worked as an engineer in Polymer Char for the past 10 years, Alejandro has acquired vast experience in polyolefin characterization techniques and instrumentation. He is involved in important research projects in the analytical department and plays a principal role in the after-sale support to Polymer Char’s customers and official partners globally.
