The LenSTM3 MALS detector offers a revolutionary approach for the measurement of molecular weight (MW) and radius of gyration (Rg) of synthetic polymers, polysaccharides, proteins, and biopolymers. A novel optical design, a unique cell-block assembly, and a new calculation methodology make the LenS3 MALS detector the first groundbreaking innovation in the light scattering technology arena in decades!
Featuring a patent pending cell geometry and a lower wavelength laser (at 505 nm), the LenS3 MALS detector allows direct measurement of molecular weight and provides best-in-class sensitivity. In addition, with a new method for utilizing the angular dependence, the determination of radius of gyration of smaller macromolecules below 10 nm in gyration size, Rg, is now possible for the first time in history!
The LenS3 MALS detector is driven by SECviewTM software, capable of multi-channel data acquisition, data processing and analysis. Totally focused around enhancing the user-interface experience, SECview is a welcoming fresh perspective that streamlines the complex calculations required by the advanced detectors and is the only GPC/SEC data processing module today that performs analysis of sample-of-interest using multiple calibration methods simultaneously.
The LenS3 MALS detector can be equipped with an optional integrated viscometer. The LenS3 MALS-V dual detector thus offers a simple and compact solution for triple detection measurements when combined with a concentration detector (RI or UV). Just like with light scattering data, the SECview software includes seamless viscometry data acquisition and processing to get the most out of advanced detection GPC/SEC analyses.
The intrinsic viscosity (IV) of polymers reflects how dense and how flexible polymer chains are in dilute solutions. The lower the IV, the more compact the polymer is while rigid polymer chains show a higher IV than flexible random coils. When combined with light scattering measurements, the MW and IV distributions provide a wealth of structural information about polymers.
