DAWN® HELEOS® II SEC-MALS Advanced Light Scattering Instrument from Wyatt Technology

The DAWN® HELEOS® II Multi-Angle Light Scattering detector is an advanced light scattering instrument designed for absolute characterization of proteins, conjugates, macromolecules, and nanoparticles.

Key Features

The key features of the DAWN® HELEOS® II are:

  • The DAWN® HELEOS® II can be used in batch mode (off-line) or can be connected on-line to an HPLC, HPSEC or AFFF.
  • It uses a 120mW solid-state laser operating at 658 nm and has on-board digital signal processing hardware for up to four external devices – RI and/or UV detectors.
  • The DAWN® HELEOS® II contains an 18-angle light scattering detector for measuring the absolute molecular weight, size, and conformation of macromolecules in solution.
  • It includes an analog output from the 90° detector for interfacing to strip chart recorders.
  • The DAWN® HELEOS® II also includes a 64,000 colour LCD display, depolarization options, and thermostatic control options.
  • It can be operated up to 210° and interfaces with high temperature GPC systems such as the GPC-IR system available from Polymer Char.
