Detection in Gel Permeation Chromatography / Size Exclusion Chromatography
Size exclusion chromatography (SEC), also known as gel permeation chromatography (GPC) is a powerful technique for analyzing the molecular weight and structure of polymers. Concentration detection is an essential component of GPC/SEC, as it allows for the determination of sample concentration at each point in the elution process. This information is used to calculate the molecular weight of the polymer.
In this webinar, our expert speakers will discuss the benefits and challenges associated with using conventional concentration detectors such as refractive index detectors. In addition, they will discuss and critique the use of the evaporative light scattering detector (ELSD) for polymer characterization. Finally, they will describe its use in conjunction with other detectors such as viscometers and light scattering detectors to provide a comprehensive study of the polymer.
