GPC/SEC Analysis with Light Scattering/Viscosity Detection

Molar mass determination in conventional GPC/SEC is based on a comparison of the retention times of the polymer with the retention times of appropriate standards of known molar mass. For polymers where no appropriate standards are available, light scattering or viscosity detection are appropriate means to derive the molar masses.

Agilent provides GPC/SEC with advanced detection techniques to analyze your macromolecular samples and obtain absolute molar masses. Often, additional structural features of the samples can also be derived. Our experts will discuss your specific requirements and will propose the most useful analytical approach.

GPC/SEC Analysis with Conventional Calibration

GPC/SEC is a widely applied technique to provide molar mass distributions and averages for macromolecular samples, allowing for easy and reliable sample comparison. In GPC/SEC, the sample components are chromatographically separated based on their size, and the elution volume is correlated to molar mass using appropriate standards of known molar mass. Agilent specialists will perform contract analysis on your macromolecular samples using conventional GPC/SEC, selecting chromatographic conditions suitable for your samples and specific analytical needs
