Low-Density Polyethylene - New insights into an old material under comparative studies

The molecular structure of low-density polyethylene (LDPE) strongly influences its applications. This study by Fraunhofer LBF and Chevron Phillips Chemical compared SEC-MALS, AF4-MALS, HT-HPLC, and 2D-LC. SEC-MALS offered key insights into branching and molecular weight, including how they impact function and depend on reactor technology.
Featured Customer: Henry Nguyen, Ph.D. – Asher Biotherapeutics
"SEC-MALS with the miniDAWN has been critical for determination of the molecular weight and polydispersity of our final material.”

Henry earned his Ph.D. in Molecular Biophysics and Biochemistry from Yale and works at Asher Biotherapeutics in protein engineering. His focus is on the developability assessment of bifunctional, glycosylated fusion proteins, with expertise in molecular biology and protein chemistry.

Determination of multiple quality attributes of antibody-oligonucleotide conjugate with SEC-MALS and AEX-MALS

The study quantifies the oligonucleotide-to-antibody ratio (OAR) and identifies molecular species, including aggregates and fragments, in two AOC samples. This approach demonstrates how LC-MALS delivers robust, reproducible measurements of key quality attributes like payload heterogeneity, supporting the development of immunotherapeutic formulations.

Live webinar on October 23rd
Colloidal fingerprints of food and beverages with multidetector AF4-MALS

Food analysis is essential for consumer safety, but traditional methods can be complex and toxic. This webinar, led by Prof. Valentina Marassi and Prof. Andrea Zattoni from the University of Bologna and byFlow srl, will demonstrate how to merge sustainability with data maximization using AF4-DAD-MALS-dRI-FLD platforms for analyzing red wine and milk.
