MOLECULAR WEIGHT DETERMINATION
Static light scattering (SLS) is a technique that leverages high precision photon counting to measure size, molecular weight, and other structural parameters. Common samples include synthetic polymers, nanoparticles, biomolecules, and other macromolecules...Read More
To obtain reliable data from your GPC/SEC instrument - each run should be related to a calibration curve obtained by measuring appropriate chromatographic standards. Calculations from GPC/SEC experiments are based on elution volume, which is a product of time and flow rate...Read More
Static Light Scattering (SLS) is capable of measuring the average molecular weight of polydisperse materials, as well as of samples with discrete aggregation numbers, such as proteins. Synthetic polymers are intrinsically polydisperse and are well-suited to direct analysis using this technique, thus the meaning of an average molecular weight is more direct...Read More
GPC (Gel Permeation Chromatography) or SEC (Size-Exclusion-Chromatography is widely acknowledged as one of the most useful characterization methods in polymer science. The technique offers the possibility to determine molecular weight distribution and its averages, to provide a complete picture of the polymer sample under investigation...Read More
The majority of modern performance polymers are designed to enhance a particular material property. A number of high-profile engineering plastics, resins, and gels are made from these kinds of precursors. Light scattering can be used to solve many of the unique problems encountered when working with unusual functional plastics and associated polymeric precursors...Read More
The specific refractive index increment (dn/dc) is a fundamental parameter for the determination of molecular weight with Static Light Scattering... Read More
