DAWN® HELEOS™ II Multi-angle Light Scattering Instrument from Wyatt Technology Corporation

DAWN® HELEOS™ II Multi-angle Light Scattering Instrument from Wyatt Technology Corporation

Description

The DAWN® HELEOS® II multi-angle light scattering (MALS) detector connects to most HPLC, GPC, FPLC or FFF separation systems to determine absolute molecular weight, size, and conformation of macromolecules and nanoparticles, in solution, without reference to calibration standards. With 18 detection angles, superb optical engineering and a range of optional add-ons, the DAWN HELEOS II provides the highest sensitivity, range of measurement and versatility of any available MALS detector.

Features:
  • Sensitivity in SEC-MALS mode: 0.2 µg BSA in PBS or comparable polystyrene in toluene
  • Range of molar mass: 500 Da to 1 GDa (may vary with molecular composition or solvent)
  • Range of rms radius Rg: 10 nm to 500 nm (up to 1000 nm with specific shape models)
  • Temperature ranges: ambient, -15°C to +150°C, and RT to +210°C models available
  • Optional integrated modules: WyattQELS™ dynamic light scattering detector for particle sizes from 1 nm to 300 nm (Rh), and the COMET™ ultrasonic flow cell cleaner
  • Options available for: laser wavelengths, fluorescence filters and polarization filters
  • ASTRA® software provides a comprehensive set of analyses for macromolecules and nanoparticles In the Product Detail table

The HELEOS II operates in combination with the Optilab® T-rEX™ or 3rd-party refractive index detector as well as the ViscoStar® II differential viscometer. In addition to chromatography mode, the HELEOS II may be used in conjunction with the Calypso® II composition gradient system in order to analyze macromolecular/biomolecular interactions without labeling or immobilization, or in batch mode (off-line) for average solution molar mass and size using syringe injection, microcuvettes or scintillation vials.
