Based on Wyatt Technology?s legacy of multi-angle light scattering (MALS) detectors, the DAWN HELEOS-II is the MALS detector with the greatest sensitivity for absolute molecular weight and size determinations of polymers and biopolymers in solution. The DAWN may be connected in series to any chromatographic system in order to determine absolute molar masses without the use of reference standards or column calibration.

The DAWN may be connected in series to any chromatographic system in order to determine absolute molar masses without the use of reference standards or column calibration.
The HELEOS-II may be ordered with precise sample temperature control from –30° C to 150°, or from ambient to 210° C and can be used with virtually any solvent: aqueous or organic. In addition, the instrument has a bright, 64,000 color LCD display that shows current system states, chromatographic conditions, operating status and more. The instrument incorporates a special 120mW gallium arsenide laser operating at a wavelength of 658 nm. This laser, together with its unique optical collimator, produces light-scattering signals superior to those obtained with any other light scattering instrument.
The DAWN HELEOS-II instruments join Wyatt Technology’s unique light scattering systems which include the miniDAWN TREOS, as well as the Optilab rEX—the only refractive index detector available that can be built to operate at any wavelength selected by the customer.
