Recent advances in polymer chemistry have led to the development of novel materials with both controlled functionality and structure resulting in unusual rheological properties. Examples include the many di- and triblock copolymer architectures and dendritic systems. These materials often include regions of different polarity and hydrophobicity and therefore represent a challenge to the analytical chemist. This application note illustrates the analysis of a star-branched polyethylene glycol with a significant hydrophobic component by aqueous SEC.
RAFA 2024: Michel Suman Discusses Food Safety And Authenticity Research
November 28th 2024During RAFA 2024, Michel Suman of Barilla Spa and Catholic University Sacred Heart talked with us about his food safety and authenticity research, focusing on contaminants, adulterants, and authenticity markers in food processing.
