Evaporative light scattering macromolecular characterization instrument DAWN® HELEOS® II

The world's most advanced light scattering instrument for absolute characterization of proteins, conjugates, macromolecules, and nanoparticles. The DAWN® HELEOS® II is the premier Multi-Angle static Light Scattering (MALS) detector for absolute characterization of the molar mass and size of macromolecules and nanoparticles in solution. The DAWN offers the highest sensitivity, the widest range of molecular weight, size and concentration, and the largest selection of configurations and optional modules for enhanced capabiliites. The DAWN is most often used in conjunction with Gel Permeation Chromatography (GPC-MALS) or Size Exclusion Chromatography (SEC-MALS) or Field-Flow Fractionation (FFF-MALS) to determine distributions of mass, size and composition independent of column calibration by reference standards. Included with each DAWN is a copy of ASTRA, the most versatile software package available for analysis of online multi-angle and dynamic light scattering.
