1. SEC-MALS:
Not all macromolecules behave alike. Polymer samples may have a different conformation than molecular standards or exhibited unexpected column interactions. As an absolute technique for determining molar mass and rms radius Rg in solution, MALS overcomes the limitations of column calibration. Multiangle Static Light Scattering (MALS) measures molar mass directly, independent of elution time.
DAWN HELEOS : the most sensitive MALS available. Includes 18 angular detectors to determine molar masses from 200 Da to 1 GDa and radii from 10-500 nm., heated /cooled option(-15C -+ 150C), and High Temperature options ( to 210C ), miniDAWN, Optilab T-rEX, ViscoStar II and WyattQELS.
2. FFF-MALS:
Field ?Flow Fractionation (FFF) is a versatile separation technique that overcomes many of the limitations of analytical SEC. Combine with MALS and/or DLS for absolute molar mass and size distributions of macromolecules and nanoparticles.
Available in two formats, Asymmetric flow field-flow Fractionation(AF4) and Hollow fiber flow field flow Fractionation(HF5) provide numerous advantages over other separation techniques.: 1nm to 1 > um. Eclipse DUALTEC and Eclispe AF4 systems.
