Determining Absolute Molecular Weight Breaking Free from Column Calibration In size exclusion chromatography (SEC), separation depends only on the hydrodynamic size of the molecules. Larger molecules are unable to penetrate the pores of the stationary phase and elute earlier, while smaller molecules enter the pores and elute later. The separation mechanism is purely physical, and no chemical or adsorptive interactions occur between the solute and the stationary phase. Traditional SEC/GPC systems without light scattering detection provide only relative molecular weight Conventional methods that...

BeSEC software is a dedicated chromatography workstation for light scattering detectors. It features a clear, user-friendly interface and straightforward operation, and delivers a wide range of application-specific reports and results. Features & Benefits • Compatible with any third-party GPC or SEC system, acquiring RI, UV, and start signals • Supports automated sequence measurements • Enables reliable multi-peak integration • Allows baseline and integration settings across all detector signals simultaneously • Provides dn/dc determination and concentration calculation • Offers statistical reports...

Specifications Polymers & Plastics Molecular weight plays a critical role in determining both the mechanical strength and processing behavior of polymers such as PET. Traditional methods like intrinsic viscosity provide only an average value and fail to reveal the complete molecular weight distribution. By integrating light scattering signals with an SEC system, researchers can directly measure absolute molecular weight and resolve the full distribution. This capability supports improved process control and product optimization, ensuring consistent quality and performance. Proteins & Biologics...
