The 1260 Infinity II Bio-SEC System is a size exclusion chromatography (SEC) system designed to meet the challenges of analyzing biological polymers. The metal-free flow path ensures robust and reliable operation for harsh analytical conditions at high salt concentrations and extreme pH values. The 1260 Infinity II GPC/SEC Column Thermostat with optional cooling ensures sample integrity. And advanced detection methods, like multi-angle light scattering with SEC MALS detection, allow for the measurement of absolute molecular weight, size, and conformation of macromolecules in solution.This unique combination makes the system the perfect solution for protein molar mass, purity, and aggregation analysis with advanced detection.
