GPC/SEC

Gel Permeation Chromatography (GPC) and Size Exclusion Chromatography (SEC) systems, a subset of liquid chromatography techniques, separate molecules based on their size in solution. This powerful analytical method uses a porous stationary phase within a column to fractionate samples, allowing larger molecules to elute faster than smaller ones. GPC/SEC equipment, from leading manufacturers like Agilent, Waters, and Shimadzu, provides precise molecular weight distributions and is essential for characterizing polymers, proteins, and other macromolecules. These systems seamlessly integrate with detectors such as refractive index (RI), ultraviolet-visible (UV-Vis) spectroscopy, and multi-angle light scattering (MALS) for comprehensive sample analysis and support workflows in polymer synthesis, biopharmaceutical development, and materials science.

GPC/SEC analyses are vital for quality control, research, and development across diverse scientific fields. Determining molecular weight and size distribution is critical for understanding polymer properties, optimizing drug formulations, and characterizing complex mixtures. Modern GPC/SEC instruments from manufacturers like Malvern Panalytical and Thermo Fisher Scientific offer advanced features like automated sample injection, temperature control, and sophisticated software for data analysis. This technology plays a crucial role in various scientific techniques including polymer characterization, protein purification, and general sample preparation for subsequent analysis like mass spectrometry. ALT carries a wide selection of pre-owned, refurbished GPC/SEC systems. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished GPC/SEC systems from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
