LenS3 MALS-V Dual Detector

LenS3 MALS-V dual detector is an integrated light scattering and viscometry detector. Combined with the EcoSEC Elite GPC system and TSKgel columns, LenS3 MALS-V offers a complete, cost-effective, high-performance approach for triple detection. In a triple-detection SEC setup, the Refractive Index (RI) detector gauges concentration, MALS provides true molecular weight and radius of gyration (Rg), while the viscometer measures intrinsic viscosity (IV). The intrinsic viscosity of polymers reflects how dense and flexible polymer chains are in dilute solutions.

When combined with light scattering measurements, the MW and IV distributions provide a wealth of structural information about polymers such as conformation (random coil, sphere, rod), density of the backbone, presence of branching (number of branches, branching frequency), hydrodynamic radius (Rh), or Mark-Houwink parameters. SECview software includes seamless light scattering and viscometry data acquisition and processing to get the most out of advanced detection GPC/SEC analyses.
