We’re excited to add Gel Permeation Chromatography (GPC) to our lab, further expanding our ability to deliver high-quality molecular weight characterization of polymers for research, product development, and quality applications.
Gel Permeation Chromatography (GPC), also called Size Exclusion Chromatography (SEC), is the gold standard for measuring polymer molecular weight distributions. This technology provides essential metrics, including the number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PD).
These results help to analyze your polymers' performance, processing behavior, and long-term stability, information key to choosing the right manufacturing technique and how it will behave during its final use.
Our GPC system can analyze a wide range of soluble polymers and oligomers, including:
Our new system is built on the Shimadzu LC-2060C 3D platform, equipped with RID-20A and photodiode-array (UV/Vis) detectors. This versatile configuration enables us to analyze a wide range of polymers with confidence and precision.
The Shimadzu LC-2060C 3D provides accurate flow, steady pressure, and precise temperature—essential for reliable GPC results. Dual detection supports both universal and selective analysis.
We adjust our GPC settings using specific polystyrene standards, which is a reliable way to find out the relative molecular We modify calibration based on polymer type, solvent, and reporting requirements.
Unsure whether your polymer meets spec — or why a formulation isn't performing as expected? Molecular weight distribution is often the answer. Talk to our chemistry team about how GPC analysis can support your development, QA, or failure investigation work.
