DAWN® HELEOS™ II

18-angle MALS light scattering detector for the measurement of absolute molecular weight, size, and conformation of macromolecules in solution. The DAWN® HELEOS™ II is the world's most advanced instrument for absolute macromolecular characterization of proteins, conjugates, macromolecules, and nanoparticles. The DAWN® may be used either for continuous flow detection following chromatographic separation (connected on-line to HPLC/ HPSEC/ AFFF) or off-line as a stand-alone unit in batch or microbatch mode.

The DAWN® HELEOS™ II utilizes a 120mW solid-state laser operating at 658 nm and also has on-board digital signal processing hardware for up to four external devices such as RI and/or UV detectors. Also contains an analog output from the 90° detector for interfacing to strip chart recorders.

The DAWN® HELEOS™ II has a gorgeous 64,000 color LCD display, thermostatic control options, depolarization options, and the ability to interface to high temperature GPC systems like the PL210 and Waters Alliance 2000. On-board analog-to-digital conversion with Ethernet communication for data acquisition.
