Microstructure Characterization of Polyolefins by Automated Cross-Fractionation Chromatography (CFC)
8 May 2011In this application note a new integrated benchtop instrument is introduced, which enables the direct measurement of the CCD x MMD surface plot in polyolefins on the order of hours and in a fully automated way. This method is capable of describing the resin microstructure without any information loss. Applications are found in all types of polyolefins when accurate knowledge of their microstructure is required.

Size Exclusion ChromatographySize exclusion chromatography (SEC) is a liquid chromatographic technique used to separate and identify molecules based on their size, including polymers, proteins, nanoparticles & nucleic acid. SEC is further subdivided into gel filtration chromatography (GFC) and gel permeation chromatography (GPC) when an aqueous or organic mobile phase is used respectively. HPLC-based SEC systems and columns are available for analytical separation alongside SEC spin columns or filters to prep samples for many protocols.

Such processes use instruments for assays like cell based assays and ELISA, for sample preparation like shakers, centrifuges and incubators, and for analysis such as sequencing and western blot analyzers. Useful features of robotic instruments include speed, reproducibility, barcode readers, software and automation.
