On request, Agilent provides contract analysis of macromolecules based on either existing guidelines, or standards provided by our customers. We treat every sample with the highest level of care while ensuring that the analysis of your samples meets the specifications provided.
Molar mass determination in conventional GPC/SEC is based on a comparison of the retention times of the analyte with the retention times of appropriate standards of known molar mass. For analytes 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 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.
If you are researching new GPC/SEC columns for a particular application or, specifically, for your new products that have not been the subject of an Agilent GPC/SEC application, the Agilent column selection service can help you choose an appropriate column, providing a suitable pore-size distribution. Our specialists will perform a GPC/SEC test on your own samples using a suitable Agilent column combination. The test report will also include chromatograms and a solvent recommendation.
